Abstract

PURPOSE:To provide the titled compsn. having excellent impact resistance, moldability and particularly excellent weld strength, by incorporating a small amount of an arom. vinyl/conjugated diene block copolymer in a compsn. consisting of a polycarbonate resin and ABS resin. CONSTITUTION:1-20pts.wt. arom. vinyl/conjugated diene block copolymer (B) such as a styrene/butadiene block copolymer is incorporated in 100pts.wt. compsn. (A) consisting of 80-20wt% polycarbonate resin and 20-80wt% ABS resin. Injection-molded articles obtd. from component A alone do not have sufficient weld strength, and are not considered to be practically satisfactory materials. By incorporating a small amount of component B, weld strength is remarkably improved.
