PURPOSE: To improve rigidity, impact strength, and heat resistance by compounding a specific multicomponent styrenic copolymer, a polyamide resin, an acrylic rubber of a core-shell type, and a modified silicone oil. n CONSTITUTION: A multicomponent styrenic copolymer having an MI of 0. 01-100g/10min is prepd. by copolymerizing 20 wt. % styrenic compd. and 5. 0-60wt.% α,β-unsatd. dicarboximide and/or 0.1-30wt.% unsatd. dicarboxylic acid (anhydride). 10-60wt.% the copolymer, 30-80wt.% polyamide resin, an acrylic rubber of a core-shell type having a mean particle diameter of 0.02-1.0μm and the shell part modified with a carboxylic acid, and 0.01-15wt.% epoxy- or amino- modified silicone oil having a viscosity (25°C) of 10-100000cSt are compounded in a ratio of the acrylic rubber to the sum of the polyamide resin and the rubber of 1-15wt.%. n COPYRIGHT: (C)1992,JPO&Japio |
