The understanding of the structure and properties of polymers in the oriented state is an important requirement in the field of polymer science and technology. This long-awaited second edition brings together an experienced international team of authors to provide the reader with an up-to-date review of the present situation, discussing all the scientific advances that have been made in this area and providing wider perspectives for this technology. As in the first edition, the emphasis is on the methodologies available for characterizing oriented polymers and their mechanical behaviour. The self-contained chapters cover a wide range of topics including the structure and morphology, mechanical properties, characterization and experimental techniques. Each chapter provides an introduction to the subject as well as a topical review of recent research.
