THERMOPLASTIC RESIN COMPOSITION.

摘要

A thermoplastic resin composition having excellent resistances to heat, impact and solvent and improved compatibility, characterized by comprising 100 parts by weight of a thermoplastic resin (A) and 0.5 to 35 parts by weight of a block copolymer (B) having aromatic vinyl compound units and isobutylene units. Preferred examples thereof include a composition comprising 100 parts by weight of a polycarbonate as the component (A) and 5 to 20 parts by weight of a styrene/isobutylene block copolymer having a styrene unit content of 10 to 45 % and an average molecular weight of 50,000 to 400,000 as the component (B).
