A process of using of a particularly substituted phenol as a chain terminator of a polymeric resin is disclosed. The chain terminator is a member selected from among ortho-substituted phenol, metha-substituted phenol, and their corresponding coupled esters. The polymeric resin is selected among polycarbonate, polyester carbonate and polyester. The thus chain terminated resin is suitable for producing molded parts and extrudates. Also disclosed are the process for producing these polymers and processes for producing the molded parts and extrudates.
