PURPOSE: To provide a composition having balanced weather resistance, impact resistance and fluidity, by blending an (ethylene propylene rubber)/(aromatic vinyl compound)/(vinyl cyanide compound) graft terpolymer with a polyolefin, etc. n CONSTITUTION: The objective composition is prepared by compounding (A) a graft terpolymer composed of an ethylene propylene rubber, an aromatic vinyl compound and a vinyl cyanide compound, (B) a polyolefin, and optionally (C) a copolymer of aromatic vinyl compound and a vinyl cyanide compound or (D) a polycarbonate resin. The molar ratio of ethylene:propylene of the EPM in the component (A) is 5:1W1:3. The aromatic vinyl compound is styrene, etc., the vinyl cyanide compound is acrylonitrile, etc. and the weight ratio of styrene/ acrylonitrile is preferably 70/30W80/20. n COPYRIGHT: (C)1984,JPO&Japio |
