PURPOSE:To obtain a resin composition having well-balanced heat resistance and impact resistance by mixing a copolymer comprising methacrylamide and a styrene with a butadiene rubber. CONSTITUTION:A resin composition comprising 60-95wt.% copolymer comprising 5-60mol% methacrylamide, 95-40mol% styrene and 0-40mol% vinyl monomer copolymerizable therewith and 40-5wt.% butadiene rubber. Said styrene refers to styrene derivatives such as p-methylstyrene, p-chloromethylstyrene and p- chlorostyrene, and they can be used alone or as a mixture. When the amount of the copolymer used in said composition is below 60wt.%, the heat resistance improving effect is small, while when it is above 95wt.%, the impact resistance is low. |
