Thermoplastic blend of polycarbonate, polymethylmethacrylate and AES

摘要

A new polymeric composition of matter comprises an intimate blend of an aromatic polycarbonate, polymethylmethacrylate (PMMA), and a terpolymer of ethylene propylene-diene (EPDM) rubber-toughened styrene-acrylonitrile (SAN). The blend of the present invention has improved physical properties and excellent environmental stress crack resistance toward organic solvents.
