PURPOSE:To provide a resin compsn. which has excellent weld strength and exhibits low dependence of impact strength on thickness, consisting of a polycarbonate resin and a specified resin. CONSTITUTION:1-800pts.wt. unsaturated epoxy monomer (e.g., glycidyl acrylate) is copolymerized with 0-2,000pts.wt. other copolymerizable monomer (e.g., styrene) in the presence of 100pts.wt. ethylene/alpha-olefin rubber (e.g., ethylene/ propylene copolymer rubber) to obtain a copolymer (a). 100-10% (by weight; the same applies hereinbelow) component (a) is blended with 0-90% copolymer (b) obtd. by copolymerizing 10-100% arom. vinyl compd. with 0-40% vinyl cyanide compd. and 0-90% alkyl unsaturated carboxylate to obtain a resin (B). 10-99% polycarbonate (A) is blended with 90-1% component B. |
