Abstract:
A polystyrenic resin composition which comprises100 parts by weight of (A) a resin obtained by mixing 100 parts by weight of a resin comprising99.9 to 90.0% by weight of (a-1) a styrenic polymer having a syndiotactic configuration and0.1 to 10% by weight of (a-3) of polypbenylene ether modified with at least one compound selected from the group consisting of maleic anhydride, fumaric acid and glycidyl methacrylate;0.005 to 5.0 parts by weight of (B) a phenolic antioxidant,0.005 to 5.0 parts by weight of (C) an antioxidant containing phosphorus, and0.005 to 5.0 parts by weight of (D) an antioxidant containing sulfur and1 to 350 parts by weight of (E) an inorganic filler, based on 100 parts by weigh of (A);wherein the phenolic antioxidant of component (B) is represented by general formula (I): ##STR4##wherein R.sup.1 represents methyl group or t-butyl group, A represents a residue group obtained by eliminating n hydroxyl groups from an alcohol having 1 to 4 hydroxyl groups and n represents an integer of 1 to 4;the antioxidant containing phosphorus of component (C) is represented by general formula (II): ##STR5##wherein R.sup.2 and R.sup.3 each independently represents an alkyl group, an aryl group, or an alkylaryl group; andthe antioxidant containing sulfur of component (D) is represented by general formulation (III): ##STR6##wherein R.sup.4 represents an alkyl group having 6, 12 or 18 carbon atoms.
