PROBLEM TO BE SOLVED: To provide a syndiotactic styrene resin composition having high toughness, particularly high elongation, while maintaining various properties such as excellent heat resistance. SOLUTION: (A) 10 to 98% by weight of a styrene polymer having a syndiotactic structure and having a weight average molecular weight of 50,000 or more and less than 300,000, (B) 90 to 2% by weight of a polyolefin having a melt index of not more than 25 at 190 ° C. and 2.16 kg, and (C) a styrene content relative to 100 parts by weight of the total of the components (A) and (B). A styrene-based resin composition comprising 0.5 to 50 parts by weight of a styrene-olefin copolymer in an amount of 40 to 85% by weight, and optionally (D) 1 to 350 parts by weight of an inorganic filler. |
