Polymeric crystals are more complex in nature than other materials' crystal structures due to significant structural disorder present. In fact, they actually exist in a semicrystalline state where the crystals are embedded in an amorphous phase to create a highly interconnected network. Presenting an in-depth and current overview of polymer crystals, Crystals and Crystallinity in Polymers provides researchers, engineers, and graduate students with guidelines to help select the proper crystallization method, evaluate polymer crystallization data, determine which methods to utilize for particular cases, and understand the different analytical techniques utilized.

This book extensively reviews Polypropylene (PP), the second most widely produced thermoplastic material, having been produced for over 60 years. Its synthesis, processing and application are still accompanied by vigorous R&D developments because the properties of PP are at the borderline between those of commodity and engineering thermoplastics. Readers are introduced to various tacticities and polymorphs of PP, and their effects on structural properties. Further, the book addresses the control of optical properties using nucleants, provides strategies for overcoming the limited cold/impact resistance of PP, examines in detail the effects of recycling, and presents guidelines for the property modification of PPs through foaming, filling and reinforcing with respect to target applications. Special attention is paid to descriptions and models of properties as a function of morphological variables. Last but not least, the book suggests potential practical applications of PP-based systems, especially in the packaging, appliances, building/construction, textile and automotive sectors. Each chapter, written by internationally respected scientists, reflects the current state-of-art in the respective field and offers a vital source of information for students, researchers and engineers interested in the morphology, properties, testing and modeling of PP and PP-based systems. The content is indispensable to the appropriate application of PPs and related composites.

The series Advances in Polymer Science presents critical reviews of the present and future trends in polymer and biopolymer science. It covers all areas of research in polymer and biopolymer science including chemistry, physical chemistry, physics, material science. The thematic volumes are addressed to scientists, whether at universities or in industry, who wish to keep abreast of the important advances in the covered topics. Advances in Polymer Science enjoys a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic, and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles, and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist. Review articles for the individual volumes are invited by the volume editors. Single contributions can be specially commissioned. Readership: Polymer scientists, or scientists in related fields interested in polymer and biopolymer science, at universities or in industry, graduate students

Fibre Structure states that each and every fibre from their manufacturing (man-made fibres) or during development (natural fibres) creates and develops its own and specialized structure. It might be the chemical structure, crystalline structure, amorphous structure and/or morphology. This structure can be modified during processing. The structure equally influences the processing conditions as well as the properties of the fibre. With this background, the present book deals with different fibres and their structures. Different aspects of structure are dealt separately in a concise and compact manner. This will serve as a reference for researchers, technologists as well as professionals as a reference book to know about the structure of different fibres and their measurement.

This volume contains an eclectic collection of 22 papers on liquid crystalline polymers presented at the Sixth Polymer Workshop, in the series sponsored by the European Science Foundation, entitled: 'Liquid Crystal Polymer Systems', in Gentofte, Denmark, 12-14 September 1983. Since a contribution to this volume was strictly voluntary, and in some cases represents a considerably expanded version of that which was presented, it is strictly speaking not correct to term this a 'proceedings'. A description of the aims and purposes of the European Science Foundation with respect to the polymer area has been presented in: Shell Polymers, Vol. 5, No.2, pp. 34-35, 1981. The papers given here represent a cross-section of current research interests in liquid crystalline polymers in the areas of theory, synthesis, characterization, structure-property relationships and applications. At least some of the current interest is motivated by attempts to practically exploit the novel properties of these materials in the developing tech nologies of high strength fibres and advanced materials for constructional purposes, but also for functional materials in the areas of information retrieval, electronics and opto-electronics applications. The editor wishes to thank all those involved for their courtesy and co-operation.

This book was developed from the papers presented at a symposium on "Water Relationships in Foods," which was held from April 10-14, 1989 at the 197th National Meeting of the American Chemical Society in Dallas, Texas, under the auspices of the Agricultural and Food Chemistry Division of ACS. The editors of this book organized the symposium to bring tagether an es teemed group of internationally respected experts, currently active in the field of water relationships in foods, to discuss recent advances in the 1980's and future trends for the 1990's. It was the hope of all these con tributors that this ACS symposium would become a memorable keystone above the foundation underlying the field of "water in foods. " This strong foundation has been constructed in large part from earlier technical conferences and books such as the four milestone International Symposia on the Properties of Water (ISOPOW I-IV), the recent IFT BasicSymposium on "Water Activity" and Penang meeting on Food Preservation by Maisture Control, as well as the key fundamental contributions from the classic 1980 ACS Symposium Series #127 on Water in Polymers, and from Felix Franks' famous seven-volume Comprehensive Treatise on Water plus five subsequent volumes of the ongoing Water Science Reviews. The objective of the 1989 ACS symposiumwas to build on this foun dation by emphasizing the most recent and maj or advanc.
