Polymer science has matured into a fully accepted branch of materials science. This means that it can be described as a 'chain of knowledge' (Manfred Gordon), the beads of the chain representing all the topics that have to be studied in depth if the relationship between the structure of the molecules synthesized and the end-use properties of the material they constitute is to be understood. The term chain indicates the connectivity of the beads, i.e. the multidisciplinary approach required to achieve the aim, knowledge, here defined as quantitative understanding of the relationship mentioned above in all its parts. Quite a few conferences are being held at which the disciplinar beads themselves are discussed in detail, and new results within their framework are presented. In this respect, the TUPAC Microsymposia in Prague have made themselves indispensable, to mention one successful example. The bi annual TUPAC Symposia on Macromolecules, on the other hand, supply interdisciplinary meeting places, which have the advantage and the disadvantage of a large attendance. Smaller-size conferences of a similar nature can often be found on a national level. The organizers of the young, but already well-appreciated, Rolduc Meetings on the interplay between fundamental science and technology in the polymer field struck an interesting chord' when they realized that focussing on the basic science behind technological problems would serve the purpose of concentration on insight along the chain of knowledge and avoid the surrender to too large a size for the meeting to really be a meeting.
The aim of the Rolduc Polymer Meetings is to stimulate interdisciplinary discussions between academic and industrial scientists and engineers. The general theme of these meetings is 'Integration of Fundamental Polymer Science and Technology'. In order to achieve this goal, experts from various fields are invited to review topics and to initiate discussions relating to future trends and developments. Since all participants are accommodated in Rolduc Abbey, a well-preserved mediaeval monument in Limburg (The Netherlands), an optimum atmosphere is provided for the exchange of ideas. About 400 participants took part in the 5th Rolduc Polymer Meeting, which was held from 29 April to 3 May 1990. This volume contains invited and selected contributed papers on topics such as thermodynamics/blends, liquid crystalline polymers, structure and morphology, polymerization and characterization. We are fully aware of the fact that the reader will not find an integrated presentation of lectures in this volume. Unfortunately, it is impossible to put down in writing the atmosphere of this and previous meetings. However, we hope that the reader will be stimulated to present his own views in forthcoming meetings after reading these proceedings. We wish to thank all contributors to this volume. P. J. L.
'Integration of Fundamental Polymer Science and Technology' is a theme that admits of countless variations. It is admirably exemplified by the scientific work of R. Koningsveld and C. G. Vonk, in whose honour this meeting was organized. The interplay between 'pure' and 'applied' is of course not confined to any particular subdiscipline of chemistry or physics (witness the name IUPAC and IUPAP) but is perhaps rarely so intimate and inevitable as in the macromolecular area. The historical sequence may vary: when the first synthetic dye was prepared by Perkin, considerable knowledge of the molecular structure was also at hand; but polymeric materials, both natural and synthetic, had achieved a fair practical technology long before their macromolecular character was appreciated or established. Such historical records have sometimes led to differences of opinion as to whether the pure or the applied arm should deserve the first place of honour. The Harvard physiologist Henderson, as quoted in Walter Moore's Physical Chemistry, averred that 'Science owes more to the steam engine than the steam engine owes to Science'. On the other hand, few would dispute the proposition that nuclear power production could scarcely have preceded the laboratory observations of Hahn and Strassmann on uranium fission. Whatever history may suggest, an effective and continuous working relationship must recognize the essential contributions, if not always the completely smooth meshing, of both extremes.
The Rolduc Polymer Meetings, of which the contents of this volume represent the third, are already on their way to occupying a unique place in the crowded calendar of symposia on every aspect of polymer science and engineering. They combine manageable meeting size with a theme, 'Integration of Fundamental Polymer Science and Technology', which is often discussed but seldom realized in practice. The technological, or applied, areas of polymers have perhaps received more emphasis historically than those of other allied disciplines. Indeed, various plastic and rubber materials were successful items of commerce long before the macromolecular concept itself was firmly established. The more fundamental aspects of the field were also largely developed in industrial laboratories. The early work of Mark and Meyer at IG Farben, and that of Carrothers and Flory at Du Pont, are good examples of this. The present situation, in which polymers are being applied to more and more demanding end uses, from high performance materials on the one hand to the biomedical and electronics fields on the other, caIls for an ever greater understanding of the basic scientific principles governing their behavior. It is evident, therefore, that interactions between those engaged in the 'pure' and 'applied' parts of the field must be promoted effectively. The Rolduc Polymer Meetings contribute significantly to such interactions, not only by interweaving technological and scientific presentations, but also by providing a forum for the participants to discuss problems of mutual interest in all their complexity.
The aim of the Rolduc Polymer Meetings is to stimulate interdisciplinary discussions between academic and industrial polymer scientists and engineers. Experts are invited to review selected topics and to initiate discussions relating to future trends and developments. The general theme of these meetings is 'Integration of Fundamental Polymer Science and Technology'. In order to serve this goal, all participants are accommodated in Rolduc Abbey, a well-preserved medieval monument in Limburg (The Netherlands) to provide an optimum atmosphere for the exchange of ideas. About 350 participants took part in the 4th Rolduc Polymer Meeting, which was held from 23 to 27 April 1989. This volume contains invited and selected contributed papers on topics such as solution properties, chemistry, emulsion polymerization, liquid crystalline polymers, structure/ morphology and blends/composites.

A gathering of leading experts in the field of high temperature polymers unite in this exciting compilation to discuss applications and marketing projections in this ever-expanding field. The authors represent a diverse group of academicians, industrial researchers, consultants, managers, and marketing forecasters and present a broad-based view of polymer technology. Topics include: liquid crystalline polymers; high temperature polyimides; heat-resistant engineering polymers; and high temperature organic polymers, including their chemistry and key functional properties in moldings, films, fibers, and coatings, as well as applications in electronics, packaging, and friction/wear. This is an essential source of data on high temperature polymers.
The third International Conference on Composite Interfaces (ICCI-III) was held under the auspecies of ASM International, The Aluminum Company of America (Alcoa), The Edison Polymer Innovation Co. (EPIC), Case Western Reserve University, Nippon Glass Fiber Co., Nitto Boseki Co., Office of Naval Reserach (ONR), SAMPE Japan, Teijin Co., Mobay Co., Union Carbide Co., and Vetrotex Sain-Gobain. The underlying philosophy of the conference continues to be the promotion of fundamental understanding of the structure and role of composite interfaces. With the growth of composite interface studies, the research direction naturally changes from characterization and understanding of interfacial structure to controlling this structure. For this reason, the conference was subtitled, "Controlled Interphase Structure." The rather unfamiliar phrase "interphase" is used to emphasize the interfacial region whose properties are different from the bulk. The importance of the interphase to the mechanochemical properties has been rapidly recognized among composite researchers in recent years. The conference incorporated nine sessions. No concurrent sessions were planned because of the strong interest among panicipants and organizers to intennix researchers from different disciplines. Papers presented were redistributed in Pans I throught V. Because of this, both the conference and proceedings are not organized based on the traditional disciplines or materials, but rather around concepts.
First published in 1996. ADHESION INTERNATIONAL 1993 is a volume of the Proceedings of the 16th Annual Meeting of The Adhesion Society, Inc. Williamsburg, Virginia, USA February 21-26,1993. This meeting featured an International Symposium on The Interphase. Interphases are extremely important in many areas of technology. They are formed when dissimilar materials are joined and they control the properties of adhesive joints, composites, coatings, and microelectronics devices. Considering the importance and scope of phenomena associated with the interphase, it was appropriate to convene such a symposium at the meeting.
Polymer composites are materials in which the matrix polymer is reinforced with organic/inorganic fillers of a definite size and shape, leading to enhanced performance of the resultant composite. These materials find a wide number of applications in such diverse fields as geotextiles, building, electronics, medical, packaging, and automobiles. This first systematic reference on the topic emphasizes the characteristics and dimension of this reinforcement. The authors are leading researchers in the field from academia, government, industry, as well as private research institutions across the globe, and adopt a practical approach here, covering such aspects as the preparation, characterization, properties and theory of polymer composites. The book begins by discussing the state of the art, new challenges, and opportunities of various polymer composite systems. Interfacial characterization of the composites is discussed in detail, as is the macro- and micromechanics of the composites. Structure-property relationships in various composite systems are explained with the help of theoretical models, while processing techniques for various macro- to nanocomposite systems and the influence of processing parameters on the properties of the composite are reviewed in detail. The characterization of microstructure, elastic, viscoelastic, static and dynamic mechanical, thermal, tribological, rheological, optical, electrical and barrier properties are highlighted, as well as their myriad applications. Divided into three volumes: Vol. 1. Macro- and Microcomposites; Vol. 2. Nanocomposites; and Vol. 3. Biocomposites.
Although polypropylene has been marketed since the 1950s, research and development in this area is still vigorous. The consumption of polypropylene over the years has been relatively high, mainly due to the steady improvement of its property profile. Polypropylene: Structures, Blends and Composites, in three separate volumes, reflects on the key factors which have contributed to the success of polypropylene, dealing with all aspects of structure-performance relationships relevant to thermoplastic polymers and related composites. Volume 1, Structure and Morphology, deals with polymorphism in polypropylene homo- and copolymers, where molecular and supermolecular structures are covered, and the processing-induced structure development of polypropylene, showing the interrelation between the processing-induced morphology and mechanical performance. Volume 2, Copolymers and Blends, contains comprehensive surveys of the nucleation and crystallisation behaviour of the related systems. It includes the development of morphology and its effects on rheological and mechanical properties of polypropylene-based alloys and blends and a review of polypropylene-based thermoplastic elastomers. Volume 3, Composites, gives a comprehensive overview of filled and reinforced systems with polypropylene as a matrix material, with the main emphasis on processing-structure-property-interrelationships. Chapters cover all aspects of particulate filled, chopped fibre-, fibre mat- and continuous fibre-reinforced composites. Interfacial phenomena, such as adhesion, wetting and interfacial crystallisation, are also included as important aspects of this subject.
