Book Description
The first edition was produced at a time when the advantages of studying oriented polymers were just becoming apparent. From a sci entific stand point it had been demonstrated that greater insight into both structure and properties could be obtained if an oriented polymer was prepared. From a technological viewpoint, major advances were under way, especially in high modulus and high strength fibres. Twenty years later, it is possible to review the scientific advances which have been made in this area and to provide much wider perspectives for the technology. As in the case of the first edition, the emphasis is on the methodologies available for characterizing oriented polymers and their mechanical behaviour. It is a particular pleasure to thank the contributing authors for their cooperation and Dr Philip Hastings of Chapman & Hall for his support and encouragement. I am also indebted to Professors A. H. Windle and D. C. Bassett for their respective contributions to sections 1. 3. 1 and 1. 3. 4. Although this chapter has been extensively revised, the contribution of the late Leslie Holliday to the first edition of this book is also acknowledged. Introduction 1 I. M. Ward 1. 1 THE PHENOMENON OF ORIENTATION Orientation in polymers is a phenomenon of great technical and theo retical importance. The word orientation itself conveys a number of ideas.
The Influence of Molecular Weight on Deformation-strength Properties of Oriented Amorphous Polymers

Book Description
Tensile tests were carried out on uniaxially oriented films of several amorphous linear polymers, i.e., polymethyl methacrylate, polystyrene, and poly-2, 2'-octamethylene-5, 5'-dibenzimidazole of different molecular weights. In the range of relatively high molecular weights, the latter were shown to have no direct effect on the mechanical properties of isotropic and oriented polymers. The mechanical properties were determined by the network structure formed during the extension, and by the average degree of orientation of the macromolecular mers. It was concluded that the formation of a particular structure is closely related to the molecular weight of a polymer, and that a given molecular weight can promote or hinder the formation of the corresponding structure under given extension conditions.

Book Description
This book is the ideal basic guide for anyone who is about to start working with metallic pigments but also contains a wealth of information for those who already use these pigments. It is hoped that this book will help existing users to achieve the best possible effects with metallic pigments and encourage those who have not yet used them to explore their potential to add value to their products.
