    Abstract: The invention relates to a styrene resin material, especially a styrene-based resin composition having good high-speed castability and good spreadability and favorable to extrusion molding lines. Of the styrene-based resin material, the product of the melt index (MI, g/10 min) and the melt tension (MT, g) measured under a specific condition is at least 20. Concretely, for example, it is a styrene-based resin composition comprising (A) from 35 to 95% by weight of a styrenic polymer having a syndiotactic structure, (B) from 5 to 50% by weight of a specific polyethylenic resin, and (C) from 0 to 15% by weight (including 0) of a specific styrene-olefin copolymer.
