Impact modified syndiotactic polystyrene blend |
摘要 |
The present invention relates to an impact resistant polystyrene composition which comprises 5 to 97% by weight of an (a) styrenic polymer having syndiotactic configuration, 2 to 95% by weight of a (b) rubbery elastomer having an olefinic component or a polyolefin, 0.5 to 10% by weight of a (c) styrene/olefin block or graft copolymer having a micro-phase separation temperature of 180 DEG C. at the highest when diluted with dioctyl phthalate to a solution with a concentration of 60% by weight and 0.5 to 5% by weight of (d) poly(phenylene ether); according to the present invention, an impact resistant polystyrene composition can be provided which is greatly enhanced in impact resistance and extensibility without impairing heat resistance and modulus of elasticity.
