    Abstract: A process for producing a graft co- or terpolymeric thermoplastic resin consisting of an ethylene-propylene rubber and an aromatic vinyl compound or of an ethylene-propylene rubber, an aromatic vinyl compound and a vinyl cyanide compound, characterized by subjecting these materials to solution polymerization in a mixed solvent comprising an aromatic hydrocarbon solvent capable of dissolving the ethylene-propylene rubber and a polar solvent capable of dissolving poly-(aromatic vinyl compound) in the case of the graft-copolymer or aromatic vinyl compound-vinyl cyanide compound copolymer in the case of the graft-terpolymer. The graft-copolymer or graft-terpolymer obtained by the present process is excellent in weather resistance and impact resistance. The impact resistance of the present graft co- or ter-polymer is not affected by processing conditions.

    Abstract: A binary or ternary graft-copolymer excellent in both tensile strength and impact resistance is obtained by the process for producing a binary or ternary graft-copolymer consisting essentially of an ethylene-propylene rubber and an aromatic vinyl compound or of an ethylene-propylene rubber, an aromatic vinyl compound, and a vinyl cyanide compound, characterized by subjecting these materials to solution polymerization in a mixed solvent comprising an aliphatic hydrocarbon solvent capable of dissolving the ethylene-propylene rubber and a polar solvent capable of dissolving a poly-(aromatic vinyl compound) or a copolymer of the aromatic vinyl compound and the vinyl cyanide compound.
