A method for the preparation of polyesters of 1,2 - to (hydroxyphenyl) - aethanen and aromatic dicarboxylic acids

摘要

A process for the preparation of polyarylene esters from aromatic dicarboxylic acids and diesters of a diphenol admixture containing 1,2- bis(4-hydroxyphenyl)ethane. The polymerization process is catalyzed by a potassium compound and yields polymer of improved color and fire safety performance.
