The invention relates to a styrene resin material,nespecially a styrene-based resin composition having goodnhigh-speed castability and good spreadability and favorablento extrusion molding lines. Of the styrene-based resinnmaterial, the product of the melt index (MI, g/10 min) and thenmelt tension (MT, g) measured under a specific condition isnat least 20. Concretely, for example, it is a styrene-basednresin composition comprising (A) from 35 to 95 % by weight ofna styrenic polymer having a syndiotactic structure, (B) fromn5 to 50 % by weight of a specific polyethylenic resin, and (C)nfrom 0 to 15 % by weight (including 0) of a specificnstyrene-olefin copolymer. |
