Improved Systhesis of Benzil End-Capped Acetylene Terminated Phenylquinoxaline Resins.

Abstract

The synthesis of two acetylene-terminated phenylquinoxaline resin systems: BA-DAB-BA, derived from 4-(3-ethynylphenoxy)benzil, 3,3'-diaminobenzidine; and BATQ-H, derived from 4-(3-ethynylphenoxy)benzil, 3,3'-diaminobenzidine, and 1,4-bis(4-benziloxy)benzene, have been substantially improved by the use of ambient temperature conditions. Both ease os synthesis and purity of product were improved. Precipitation conditions were developed for BATQ-H which lowered the content of BA-DAB-BA, permitting tailoring of the average length for processing and mechanical properties studies.
