Ring-forming Polymerizations is a part of a volume that features a complete review and compilation of ring-forming polymerization reactions that result to heterocyclic ring formation. This book shows relevant growth in terms of research and commercial development in the area of polymer chemistry. This volume is comprised of four major chapters and is organized according to the specific heterocyclic ring structure resulting from ring-forming polymerizations. Each of the chapters is arranged further according to the polymer type and the different methods used in the preparation of that type, where emphasis is given to synthetic methods. This book specifically discusses the linear polymers that were intentionally made. Also, the structures presented are limited in scope considering that they are the result of the research cited in this book. However, claims that dispute a certain structure found in the research are also included to provide balance, fairness, and objectivity. Specifically, this book is a valuable resource for polymer and organic chemists. However, it can also be of great use to those scientists and researchers interested in the study of polymer chemistry of living systems.
Ring-Forming Polymerizations, Part B, 1: Heterocyclic Rings presents a comprehensive review and compilation of ring-forming polymerization reactions that proceed with the formation of heterocyclic rings. Emphasis is placed on polymerizations leading to linear, high molecular weight products. This book is comprised of three chapters and begins with a discussion on polymerizations that result in the formation of a multiple bond containing at least one heteroatom. The condensation of amines with carbonyl compounds to yield poly(Schiff bases) and related polymers is examined, along with other carbon-nitrogen double bond-forming polymerizations. The next chapter is devoted to the polymerization of rings containing two carbon atoms, including the polymerization of polyphenols with diboronic acids and that of diisocyanides with triorganoborons. The last chapter describes the polymerization of rings containing three carbon atoms, with particular reference to polyisoxazoles and related polymers, polythiazoles, polyimidazoles and related polymers, polypyrazoles, and polytriazines. This monograph will be of interest to polymer and organic chemists and others who are concerned with the polymer chemistry of living systems.

Polymerization of Heterocycles (Ring Opening) is a collection of papers presented at the International Symposium on Polymerization of Heterocycles (Ring-Opening) held in Warsaw, Poland on June 23-25, 1975. The first paper describes the developments and physical meaning of ion pairs and higher ionic aggregates. Another paper explains the process of obtaining linear polymers, containing rings in the main chain. The book interprets the various behaviors of polymers that can result in high optical yields of stereoelectivity ratios equal to 8. The text then discusses future trends in aldehyde and carbonyl polymerization, including some problem areas pertaining to failures to homopolymerize or copolymerize tetrachloroethylene oxide. Another paper reviews the elemental reactions of selected combinations of copolymerization; the next paper discuses aspects of the mechanism of nucleophilic opening of epoxide rings through studies of certain kinetics. The book then analyzes the ability of lactams to undergo ring-opening polymerization, which mainly depends on the ring size and on the substitution and presence of heteroatoms in the lactam ring itself. The text also discusses the preparation, properties, and applications of the heterochain polymers in medicine or biologically active materials. The book can provide useful information for biochemists, researchers dealing with inorganic and organic compounds, and scientists working in the fields of chemistry such as synthetic chemistry, as well as polymer engineering.
Many commercially important sub-categories exist under the polyarylether heading. Starting with polyphenylene ethers, the list includes poyarylethersulfones, polyaryletherketones, and polyetherimides. This handbook provides a database of these polymer families for researchers and plastic industry professionals who need a comprehensive reference on the structures and properties that have been achieved from this polymer class. Key features include tabular databases for the polyarylethers that have been synthesized, a collection of published procedures for the synthesis of polyarylethers, and a guide to their "engineering properties" as published by the manufacturers of the commercialized polyarylethers.
