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. 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.l.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.
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.
Properties of Polymers: Their Correlation with Chemical Structure; Their Numerical Estimation and Prediction from Additive Group Contributions summarizes the latest developments regarding polymers, their properties in relation to chemical structure, and methods for estimating and predicting numerical properties from chemical structure. In particular, it examines polymer electrical properties, magnetic properties, and mechanical properties, as well as their crystallization and environmental behavior and failure. The rheological properties of polymer melts and polymer solutions are also considered. Organized into seven parts encompassing 27 chapters, this book begins with an overview of polymer science and engineering, including the typology of polymers and their properties. It then turns to a discussion of thermophysical properties, from transition temperatures to volumetric and calorimetric properties, along with the cohesive aspects and conformation statistics. It also introduces the reader to the behavior of polymers in electromagnetic and mechanical fields of force. The book covers the quantities that influence the transport of heat, momentum, and matter, particularly heat conductivity, viscosity, and diffusivity; properties that control the chemical stability and breakdown of polymers; and polymer properties as an integral concept, with emphasis on processing and product properties. Readers will find tables that give valuable (numerical) data on polymers and include a survey of the group contributions (increments) of almost every additive function considered. This book is a valuable resource for anyone working on practical problems in the field of polymers, including organic chemists, chemical engineers, polymer processers, polymer technologists, and both graduate and PhD students.
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.
Volume three deals specifically with the role of monomers and resins in radiation curing. The nature of the backbone of ologomers leads to the ultimate physical or chemical properties of the UV-cured material. This chapter also covers aspects of the chemistry of these compounds in relation to their end uses.
Heterophase polymerization is a century-old technology with a wide range of relevant industrial applications, including coatings, adhesives, rubbers, and many other specialized biomedical and high-performance materials. However, due to its multiscale complexity, it still remains a challenging research topic. It is a broad field covering all heterogeneous polymerization processes that result in polymer dispersions. Its technical realizations comprise emulsion polymerization, dispersion polymerization, suspension polymerization, miniemulsion polymerization, microemulsion polymerization, and others. This book is devoted to the science and technology of heterophase polymerization, considering it a generic term as well as an umbrella expression for all of its technical realizations. It presents, from a modern perspective, the basic concepts and principles required to understand the kinetics and thermodynamics of heterophase polymerization at the atomistic, molecular, macromolecular, supramolecular, colloidal, microscopic, mesoscopic, and macroscopic scales. It critically discusses the important physicochemical mechanisms involved in heterophase polymerization, such as nucleation, particle aggregation, mass transfer, swelling, spontaneous emulsification, and polymerization kinetics, along with the experimental evidences at hand.

Control the development of polymer crystals with this groundbreaking introduction Polymer crystallization is a crucial component of polymer development that impacts processing, applications, presentation, and more. Intervention in the polymer crystallization process, in the form of nanofilters, compatibilizers, and more, has the potential to improve optical and chemical properties, improve degrees of crystallinity, and increase hardness of polymer composites. The myriad applications of crystalline polymers make this one of the most exciting and fast-growing fields in polymer research. Polymer Crystallization provides a comprehensive introduction to this field and its most important recent developments. It characterizes and analysis an expansive range of crystalline polymers and discusses possible mechanisms for influencing their crystallization processes to impact a variety of outcomes and applications. These applications include industries from food packaging to automotive parts to medical and aerospace materials. Polymer Crystallization readers will also find: Detailed treatment of polymer morphology, rheology, modeling, and more Thorough introduction to the fundamentals of polymer crystallization Discussion of environmental safety issues and avenues for future research Polymer Crystallization is a useful reference for materials scientists, polymer scientists, biomedical scientists, and advanced undergraduate and graduate students in these and related fields.
