ABSTRACT OF THE DISCLOSURE The present invention relates to a styrene-based resin composition comprising (A) a styrene-based polymer having mainly a syndiotactic configuration and (B) a phosphorus-containing antioxidant and a phenolic anti- oxidant wherein the total amount of the phosphorus- containing antioxidant and the phenolic antioxidant compounded is 0.005 to 5 parts by weight per 100 parts by weight of the styrene-based polymer, and the weight ratio of the phosphorus-containing antioxidant to the phenolic antioxidant is 100:1 to 0.3:1. According to the present invention, a styrene- based resin composition having excellent heat stability can be obtained. Further, fibrous molding which is excellent in heat resistance, chemical resistance and so on or molding which is excellent in heat resistance and mechanical strength is provided by spinning or stretching the above composition.
