PURPOSE:To obtain the titled resin composition, having excellent heat resistance, mechanical strength and solder heat resistance and suitable as connectors, tuners, by blending polyphenylene sulfide with an unsaturated carboxylic acid (derivative) graft-modified polyolefin in respective specific amounts. CONSTITUTION:A composition obtained by blending 100pts.wt. total of (A) 5-85wt.% polyphenylene sulfide having 50-50,000P melt viscosity and (B) 15-95wt.% modified polyolefin, prepared by graft modifying a polyolefin (e.g. poly-4-methyl-1-pentene) with an unsaturated carboxylic acid (derivative) at 0.01-10wt.% grafting amount and having >=200 deg.C melting point with (C) 10-60 pts.wt. reinforcing fibers (e.g. glass fibers) and, as necessary, (D) 5-30pts.wt. oxazoline-modified polystyrene. |
