Thermoplastic polymer composition

Abstract

Abstract PURPOSE: To prepare the titled composition giving a molded article having excellent impact strength, delamination strength, paintability, etc., by compounding a thermoplastic polymer with a block copolymer composed of a vinyl aromatic compound and a conjugated diene compound and modified with a dicarboxylic acid. CONSTITUTION: The titled composition is prepared by kneading and mixing (A) 100pts.wt. of one or more thermoplastic polymers selected from (a) a polyoxymethylene polymer, (b) a polycarbonate polymer or its modified product, (c) a polysulfone polymer or its modified product, (d) a nitrile polymer, (e) a polyphenylene ether polymer or its modified product, and (f) a polyarylene sulfide polymer or its modified product, with (B) 1W100pts.wt. of a modified block copolymer or its ionically crosslinked product, obtained by the addition reaction of 0.05W20pts.wt. of an unsaturated dicarboxylic acid or its derivative to 100pts.wt. of a block copolymer composed of a vinyl aromatic compound (esp. styrene) and a conjugated diene compound (esp. butadiene) at a wt. ratio of 5:95W95:5.
