Crystalline Polymers

  • Chapter
Polymer Physics

Abstract

Crystalline polymers have a ‘reasonably’ regular chain structure and a specific preferred chain conformation. The presence of chain defects, e.g. atactic sequences and/or chain branches at high concentrations, makes it impossible for the polymers to crystallize and on cooling they ultimately form a fully amorphous glass. There are exceptional cases of crystalline atactic polymers due to side-group crystallization or to the small size of the pendant group. The hydroxyl group in poly(vinyl alcohol) is, for example, sufficiently small and the atactic polymer is crystallizable. Polymers with a small proportion of chain defects crystallize to a lower overall crystallinity than that of the polymer containing no chain defects. The chain defects are normally confined to the amorphous component. Small groups may, however, be housed within the crystals.
