Versuchsvorschrift

70 Parts by weight of a powdery polyphenylene sulfide resin (Tohpren T-4 produced by Tohpren Co., Ltd ; average particle size, 50 μm), 30 parts by weight of a polyester composed of cyclohexanedimethanol and terephtalic acid (polycyclohexanedimethylene terephthalate (hereinafter referred to as PCT); [η]=0.9), which is a thermopalstic polyester, 12 parts by weight of an unsaturated polyester obtained from ethylene glycol and maleic acid anhydride ([η]=0.2), 6 parts by weight of styrene and 1 part by weight of benzoyl peroxide were mixed. The mixture was extruded through a twin-screw extruder (Werner Pfleiderer 30 Φ) at a barrel temperature of 30° C. and pelletized on a pelletizer.
