Degradable polymers and materials : principles and practice / par Khemani, Kishan. Publication : [S.l.] : An American Chemical Society Publication, 2006 . 456 p. ; , This book is an excellent guide to biobased and biodegradable polymeric materials. It summarizes current knowledge on polymer degradation mechanisms and provides insight into recent, state of the art syntheses of (bio)degradable polymers. The book captures the shift that is currently observed in polymer industries, which takes the industry from a strict petroleum-based business to an industry that starts to incorporate biobased raw materials and seeks actively to manufacture materials that are environmentally benign. The book describes various aspects of current polymer research with special emphasis on natural polymers, syntheses and modifications of polyesters and characterization technologies that allow to elucidate degradation mechanisms. The understanding of polymer degradation is not limited anymore to hydrolytic processes, this book captures new approaches to the degradation of plastic materials ranging from photodegradation to the regulation of genes of polymer-degrading microorganisms. A profound part of the book is dedicated to poly(lactic acid) a polymer that is now produced in large scale from renewable resources, the modification, copolymerization, application and engineering of this material is discussed in detail and a comprehensive review is provided. 24 cm. Date : 2006 Disponibilité : Exemplaires disponibles: La bibliothèque des sciences de l'ingénieur (1),

Liquid crystal elastomers / par Warner,, M. Publication : [S.l.] : Oxford University Press, USA, 2003 . 424 p. ; , Liquid crystals are fluids with directionality defined. Polymers are long molecules with a shape that can be changed. As a network, polymers form rubber-a soft solid that is locally liquid-like and capable of huge extension. Liquid crystal elastomers area combination of all these curious aspects, but with additional, revolutionary new phenomena-for example, spontaneous shape changes of several hundred percent induced by temperature change, with equally large opto-mechanical responses, shape change without energy cost (Soft elasticity), color change with strain, lasing and photonics, sensitivity to molecular handedness and soft solid ferroelectricity. This book is a primer for liquid crystals, polymers, rubber and elasticity. It then describes the theory and experiment of these remarkable materials for the first time as a monograph. Worked examples are solved so that the reader can become proficient in the field himself. The book is directed at physicists, chemists, material scientists, engineers and applied mathematicians at the graduate level and beyond. 24 cm.

Principles of polymer science, second edition / par Bahadur, P. Publication : [S.l.] : Alpha Science International, Ltd, 2005 . 436 p. ; , Principles of Polymer Science introduces several basic and advanced aspects of polymers for the undergraduate and graduate students in chemistry, chemical engineering and materials science. The second and thoroughly revised edition includes the technical aspects of synthesis, characterization, behaviour and technology in a straightforward and lucid manner. Separate chapters on natural, inorganic and specialty polymers would attract readers from interdisciplinary courses. 25 cm.
