POLYPHENYLENE SULFIDE RESIN COMPOSITION AND PLASTIC ARTICLE

摘要

A polyphenylene sulfide resin-based composition is provided to significantly reduce burrs generated during molding while maintaining good physical properties such as mechanical strength and processability, and to obtain molded plastic articles used in optical parts, electric/electronic parts, etc. A polyphenylene sulfide resin-based composition comprises: a base resin containing 60-95 wt% of a polyphenylene sulfide resin, and 5-40 wt% of a polyphenylene ether resin; and 0.01-5.0 parts by weight of a disulfide compound based on 100 parts by weight of the base resin. The polyphenylene sulfide resin has a melt index of 10-300 g/10 minutes at 316 deg.C under a load of 2.16 kg. The polyphenylene ether resin has an intrinsic viscosity of 0.2-0.8 in chloroform at 25 deg.C.
