Linear polymers of 4,4′‐(2,2‐butylidene)dibenzoic acid

摘要

AbstractPolyesters and polyamides have been prepared and characterized from 4,4′‐(2,2‐butylidene)dibenzoic acid. The polymers are amorphous with the exception of the piperazine polyamide. This novel diacid yields hard, tough polymers. The properties of the ethylene glycol and bisphenol A polyesters have been thoroughly investigated and are rep
