Terpolymer having aliphatic polyester, polysiloxane and polycarbonate

摘要

Block condensation copolymers with improved processability, low temperature impact strength and solvent resistance have a polysiloxane block such as 120, and a polycarbonate-aliphatic polyester block. Such polymers are made by an interfacial reaction of phosgene with a bisphenol, a phenol-terminated siloxane, and an aliphatic dicarboxylic acid salt.
