Book Description
Macromolecular Microsymposia – 16 (Prague, 1976) is a collection of lectures presented at the 16th Microsymposium on Macromolecules (Advances in Scattering Methods), held in Prague on July 12-16, 1976. This book contains four chapters and begins with a survey of density fluctuations in amorphous and semicrystalline polymers. The next chapter provides experimental procedures for studying light scattering from polymer films. This chapter also describes the theory for scattering from spherulites and the procedures for correction for multiple scattering, truncation, and disorder, and illustrated for studies n polyethylene terephthalate films. These topics are followed by a discussion of the classical light scattering from polymer solutions. The last chapter considers the progress of techniques and instruments of light-scattering spectroscopy, with emphasis on advances made in photon correlation. This book will be of value to analytical and organic chemists and researchers.

Book Description
Macromolecular Microsymposia–XII and XIII provides information pertinent to the fundamental aspects of polymers and polymer solutions. This book discusses the structures in polymer solutions and the transformations of functional groups in polymers. Organized into two parts encompassing 15 chapters, this book begins with an overview of the method for the determination of the structure of block copolymers in concentrated solution and in the dry state. This text then examines the liquid crystalline mesophases of the cholesteric type where one requirement is the existence of chiral single molecules. Other chapters consider phospholipids and glycolipids, which are significant component of the structure of many cell membranes. This book discusses as well the organized structures of some synthetic macromolecules in gels and solutions. The final chapter deals with the technique for studying the effect of the excluded volume on the probability of cyclic chain conformations. This book is a valuable resource for chemists.

Book Description
"Polymer Science and Engineering: Challenges, Needs, and Opportunities," a report issued in 1981 by the National Research Council's ad hoc Panel on Polymer Science and Engineering gives ample support for the urgent need of increased commitment to basic studies on polymers. Needs and opportunities, mentioned in the Panel's list, included polymerization methods, specialty polymers, high performance materials, and in situ (reaction injection molding) polymerization for direct conversion of monomers/oligomers to useful shapes. Clearly, in all these and several other areas, advances in polymer synthesis are needed. Whether one takes a look at the commodity or specialty polymers area or considers areas of growing needs, such as polymers for the automotive, aerospace, electronics, communications, separations, packaging, biomedical, etc., advances in polymer synthesis are needed. Polymeric materials, as they are constantly being modified and improved, fine-tuned for current and additional needs, and more readily adopted by industry and the public, will have a vastly expanding influence on everyday life. However, lack of long-term support of meaningful size for basic research on all facets of polymer chemistry and engineering, with particular emphasis on making needed advances in polymer synthesis, could well stunt the growth of high techn.ology in our country. Expanding this thought, lack of attention to basic research on polymer synthesis could help foster or insure that we won't have materials with performance profiles to meet requirements of emerging technologies and national needs, in a reasonably economic and timely fashion.
