PURPOSE: To prepare the titled composition having balanced and excellent high- temperature mechanical properties, appearance of the molded article, and heat resistance, and good extrusion stability and moldability, by compounding a polyester resin with fibrous or granular reinforcing agent in combination with a high molecular polyphenylene sulfide. n CONSTITUTION: 100pts.wt. of a thermoplastic polyester is compounded with 5W 150pts., pref. 10W130pts. of fibrous and/or granular reinforcing agent and 5W 100pts, pref. 10W80pts. of polyphenylene sulfide having a weight average molecular weight of 20,000W50,000 and a melting point of 270W290°C. The polyphenylene sulfide can be prepared by maintaining a sulfur-donative compound such as a thiosulfate and p-dihalogenobenzene under the polymerizing conditions in the presence of an alkali metal acetate. n COPYRIGHT: (C)1982,JPO&Japio |
