Abstract
There is disclosed a styrene-based polymer composition which comprises (A) 10 to 98% by weight of a styrene-based polymer having syndiotactic configuration with a racemic pentad of 30% or more and (B) 90 to 2% by weight of polyphenylene ether having an inrinsic viscosity of 0.28 dl/g or more at 30.degree. C. in chloroform. Also, a flame retarder, a flame-retardant aid, a rubber-like elastomer or an inorganic filler may optionally be added to the composition. Further, also disclosed is a stretched molding comprising stretching the above composition.
Claims7
A stretched molding formed by stretching a molding of a styrene polymer composition comprising
- (A) 10 to 98% by weight of a styrene polymer having sydiotactic configuration with a proportion of a racemic pentad of 30% or more and
- (B) 90 to 2% by weight of a polyphenylene ether having an intrinsic viscosity of 0.28 dl/g or more at 30.degree. C. in chloroform.
