发明名称 RESIN CRYSTALLIZATION PROMOTER AND RESIN COMPOSITION
摘要 The present invention relates to a method for producing a resin composition having a crystallized and orderly arranged structure. The method comprises kneading an amorphous thermoplastic resin with a resin crystallization promoter to form a mixture, wherein the resin crystallization promoter comprises vapor grown carbon fibers, each fiber filament of the carbon fibers having a diameter of 0.001 mum to 5 mum and an aspect ratio of 5 to 15,000, the fibers having undergone a graphitization at 1,500° C. or higher, and subsequently subjecting the mixture to annealing at a temperature of from 55° C. higher than the glass transition point of the resin to a temperature 75° C. higher than the glass transition point of the resin. The crystallization promoter and annealing provide a thermoplastic resin composition, which, when molded, exhibits improved strength and tribological characteristics.
