Giant Molecules Raymond B. Seymour and Charles E. Carraher Our modern life-style depends on polymers found in protein, DNA, cellulose, starch, polyesters, nylon and countless other materials. Giant Molecules, the first readily understandable book for the nonscientist concerned or curious about these essential materials, takes an holistic approach that connects polymers to everything from viruses, superconductivity, and genetic engineering to various types of plastics and foams, incorporating basic technical information in a readable form that helps even the novice understand the structure and use of all polymers. This book serves as a natural vehicle for conveying the importance and excitement of science. 1990 (0 471-61532-3) 336 pp. Impact Modifiers for PVC The History and Practice John T. Lutz, Jr. and David L. Dunkelberger Presents the subject of impact modification of PVC from its beginnings to the most recent developments, treating all aspects of PVC impact modification with unmatched depth and detail. In clear, readable language, impact theories are discussed to explain PVC's unique macromolecular structure and to illustrate how this makes it possible to toughen the material with various modifiers. For the neophyte and seasoned practitioner, the book provides real-world guidance in formulating tough PVC for a wide variety of applications. The thorough summary and appendix present an unprecedented compilation of impact modifier literature and patents. 1991 (0 471-52764-5) 224 pp.
