Copolycarbonate composition with high stress cracking resistance, used for electrical component housings, comprises thermoplastic aromatic copolycarbonate including 4,4'-dihydroxybiphenyl units, and a rubber grafted with vinyl monomers

摘要

Copolycarbonate composition comprises: (a) a thermoplastic aromatic copolycarbonate including 4,4'-dihydroxybiphenyl units; and (b) a rubber grafted with vinyl monomers. Copolycarbonate composition comprises: (a) a thermoplastic aromatic copolycarbonate derived from a bisphenol mixture consisting of 4,4'-dihydroxybiphenyls of formula (I) (0.1-46 mol.%) and other bisphenols (54-99.9 mol.%) (2-98 parts by weight, (pbw)); and (b) a graft compolymer consisting of vinyl monomer(s) (5-90 wt.%) and a rubber with a glass transition temperature of 10 deg C or less (10-95 wt.%) (1-50 pbw). R1 - R8 = H, halo, 1-8C alkyl, 1-5C cycloalkyl, 6-10C aryl or 7-12C aralkyl.
