The polydiacetylenes are a class of polymers that are attrac ting increasing attention worldwide. There are many reasons for this interest one of the most important being the availability of many polydiacetylenes as macroscopic, high quality, single crystals. This fact was first reported in the pioneering work of Prof. G. Hegner on the solid-state polymerization of disub stituted diacetylenes in the late 1960s. Since then studies of the polymerization process and the properties of monomers and polymers have advanced understanding of solid-state reactivity and the physiCS of quasi-one-dimensional materials. More recently work on soluble polydiacetylenes, gels and films has been of interest for both academic and technological reasons. Progress in this area has required a combination of research disciplines ranging from synthetic organic chemistry to solid state physics. The interdisciplinary effort required for success ful research in polydiacetylenes was reflected in the mix of chemists, physicists and materials scientists who attended the Workshop. The emerging potential for commercial applications of polydiacetylenes was also evident in the nearly equal partici pation of academic and industrial/government scientists. The WOrkshop was the first major international meeting to focus solely on polydiacetylenes. It provided a forum in which problems of mutual interest could be discussed by scientists with diverse backgrounds and interests. It also satisfied the need for a review of the science of these materials at a time when this basic understanding is leading to technological applications.

The organization of polymers near defects is a general question of both scientific and technological interest. The relationship between microstructure and properties must involve a discussion of defects. But defects in macromolecular materials are not as clearly defined as in more ordered systems. Schemes to classify defects must rely on the symmetry of the phase, the dimensionality of the defect and the nature of the deformation induced. Several researchers such as Kleman (1983) and Wunderlich (1973) have classified macromolecular defects using these constraints. Defects in polymer systems have not been thoroughly studied because of difficulties in imaging the local regions around defects in organic materials with high energy electron beams. Also, defects are difficult to isolate and study in detail because most polymer systems have a intermediate amount of disorder present in the bulk structure.

Chromogenic materials change their optical properties in response to an external stimulus. Due to their potential applications as light valve (e.g., in sun protecting glazing) or as temperature sensor, thermotropic, and thermochromic materials have come more and more into the focus of research and development. Commercialization of such high-tech products has already started and certainly many others will enter the market in near future. This book is the first to give an overview of the scientific and applicative aspects of the entire class of thermochromic and thermotropic materials. It discusses the origin of the thermo-optical effects at the molecular level and presents the macroscopic optical and material properties of chromogenic materials as well as their present and potential future application. With a view to particular potential applications, the book outlines the specific development strategies of these materials. The book addresses scientific and application-oriented researchers as well as students in the fields of smart adaptive polymers and sun-protecting materials. By providing the fundamental knowledge and outlining the future trends of thermochromism, this book familiarizes the readers with the entire field of the phenomenon.

A compact but comprehensive review of the most important preparative methods for the synthesis and chemical modification of polymers. The contents of the two-volume handbook (Part A was cited in the May 1992 SciTech Book News) are subdivided according to the chemical structure of the polymer backbone on the one hand (Chapters 1-14 of Part A and 15-18 of Part B) and special properties and applications of polymers regardless of their chemical structure on the other hand (Chapters 19-27 of Part B). The latter chapters deal with, for instance, electroconductive polymers, polymeric reagents, and models of bio-polymers. Includes some 11,000 references to the original literature.
