Novel thermoplastic resin composition

Abstract

Abstract PURPOSE:A molding material not causing lamellar release of molded article, having improved mechanical properties, wear resistance, chemical resistance, and heat resistance, obtained by blending a copolymer containing an imide compound of an unsaturated dicarboxylic acid with polyamide and a thermoplastic resin. CONSTITUTION:(A) A copolymer (preferably a styrenic or an unsaturated carboxylic acid ester copolymer) containing 1-30mol% imide compound of alpha,beta-unsaturated dicarboxylic acid as a copolymer component is blended with (B) a polyamide, especially one having a molecular weight of 15,000-40,000 and (C) a thermoplastic resin (e.g., styrenic resin, or polycarbonate resin) as a third component under sufficient shear stress at 220-330 deg.C in a molten state. In the amounts of the components, the amount of the copolymer obtained by the high polymer reaction of the component A and the component B is an amount wherein it is dispersed as particles having diameters <=15mu into the composition (the amount of the copolymer is >=10wt%), the amount of the component A is 5- 70wt%, that of the component B is 5-80wt% and that of the component C is 10-90wt%.
