Description: This book is concerned with the detailed structure and properties of the solid state of crystalline polymers. The application of electron microscopy to crystalline polymers has pointed out that a vast amount of detailed morphological information is susceptible to study and description; that which has been reported is the subject of this book. In addition, through the joint application of microscopy and such other techniques as detailed studies of mechanical, dielectric, and nuclear relaxations and x-ray diffraction, the initial steps toward the description of polymers on a molecular scale are occurring–descriptions in terms of features such as twinning, slip, dislocations, defects, and the like, which are familiar as a result of their use in the solid state physics of atomic solids.
It is hoped that the results presented in this book will not only stimulate further research in the area of morphology but will also serve as a basis to permit the development of the foundations of the solid-state physics of polymers.
