ABSTRACT In accordance with the present invention, there are provided fiber reinforced heat-resistant polyolefin compositions comprising 5-85% by weight of polyphenylene sulfide (A), 15-95% by weight of modified polyolefin (B) having a melting point of above 200°C, which has been graft-modified, either partly or wholly, with 0.01-10% by weight of unsaturated carboxylic acid or if derivative, 10-60 parts by weight, based on 100 parts by weight of (A) + (B), of reinforcing fiber (C) and, if necessary, 5-30 parts by weight, based on 100 parts by weight of (A) + (B), of oxazoline-modified polystyrene (D). The compositions thus provided are excellent in heat resistance, water resistance, moisture resistance and solderability, and that excellent in mechanical strength.
