ABSTRACT:
Highly unusual and useful novel high-performance, oriented, low-crystalline, essentially heterocyclic structures, e.g. films, are prepared from certain novel and important process sequences. These structures, e.g. films and fibers, possess a unique combination of minimal shrinkage at high temperatures, after orientation, coupled with negligible coefficient of expansion over an unusually wide temperature range.
