Impact-resisting resin composition

Abstract

Abstract PURPOSE: A resin composition with excellent impact resistance, obtd. by mixing a copolymer prepd. from an alkynyl arom. monomer and an unsaturated dicarboxylic anhydride with a 1,2-polybutadiene, an arom. vinyl-conjugated diene block copolymer, etc. CONSTITUTION: A copolymer (A) obtd. by the polymer of 100W70wt% monomer such as an alkenyl arom, monomer, e.g. styrene or an unsaturated dicarboxylic anhydride, e.g. moleic anhydride with 0W30wt% rubber-like polymer is mixed with a 1,2-polybutadiene (B) of the degree of bonding 5W50% and intrinsic viscosity ≥0.7, contg. 70% or more 1,2-bond constitution and an arom. vinyl-conjugated diene block copolymer (C) in a wt. ratio of A:B+C of 60W95:40W5 and B:C of 50W10:50W90, or with a hydroxy or amino group-contg. polymer (D) in a wt. ratio of A:D of 60W95: 40W5 to prepare the title resin composition.
