Abstract
Provided is a syndiotactic polystyrenic resin composition, of which the resin moiety comprises any of (A) a syndiotactic styrenic polymer (B) a rubber-like elastomer having affinity for the component (A), (E) a polymer having compatibility with or affinity for the component (A) and having a polar group, (F) a thermoplastic resin except (A), and (G) a polyolefin having MI of at most 25, and which contains from 10 to 350 parts by weight, relative to 100 parts by weight of the resin moiety, of (C) a fibrous filler, and from 10 to 350 parts by weight, relative to the same, of (D) a tabular filler having a mean grain size of from 4 to 700 &mgr;m and a mean aspect ratio of from 12 to 120. Moldings of the composition have good impact resistance and warp little, still having good heat resistance and other good properties intrinsic to styrenic resins.
