Organic optical component

摘要

A low birefringent organic optical component prepared from a resin consisting essentially of one or more repetitive structural units selected from the group consisting of structures represented by general formula (1); wherein A is either of the groups below. The organic optical component can exhibit excellent transparency, heat resistance and mechanical strength as well as a low birefringence. Also provided is a novel aromatic polyamide with a low permitivity and excellent transparency, processability and thermal stability, besides excellent heat resistance inherent in an aromatic polyamide.
