CARBOXY-FUNCTIONALIZED POLYCARBONATES AND METHOD OF PREPARATION

摘要

CARBOXY-FUNCTIONALIZED POLYCARBONATES AND METHOD OF PREPARATION Carboxy-functionalized polycarbonates are prepared by incorporating a carboxylic acid-substituted phenol, preferably t-butyl p-hydroxybenzoate, as a chainstopper in a polycarbonate-forming reaction The products are capable of forming copolymers with other polymers such as polyamides and functionalized olefin polymers, by generation of a carboxy group which reacts therewith.
