This book describes the synthesis, structure and properties of the polyamide family known by the common term n-nylon. Both the chemistry and physics are combined, making it a unique contribution to literature in this field. After general chapters on thermodynamics, polycondensation and crystallinity, all nylons from n=1 to n=22 are discussed in detail and the book concludes with chapters discussing the similarities of different nylons and their technologically important properties.
