Impact resistant polystyrene composition |
摘要 |
There is disclosed an impact resistant polystyrene composition which comprises 5 to 98% by weight of an (a) styrenic polymer having a syndiotactic configuration and 2 to 95% by weight of a (b) styrene/diolefin diblock copolymer, styrene/diolefin/styrene triblock copolymer or styrene/diolefin random compolymer, each having a hydrogenation rate of 70 to 98 mol %, and optionally a (c) rubbery elastomer having an olefinic component or polyolefin, a (d) poly(phenylene ether), etc. The above composition is greatly enhanced in its impact resistance and elongation properties without deterioration of heat resistant stability of color tone, etc.
