Abstract

Para-ordered aromatic heterocyclic polymers containing pendant phenyl groups along the polymer chain backbones. The polymers possess a high degree of thermal stability that renders them particularly useful in high temperature applications such as in the fabrication of plastics, composites and fibrous materials.
