Abstract of the Disclosure A modified polyphenylene sulfide resin is produced by the steps of mixing a polyphenylene sulfide resin with at least one silane compound selected from the group consisting of vinylalkoxysilanes, epoxyalkoxysilanes, aminoalkoxysilanes and mercaptoalkoxysilanes and kneading the mixture at a temperature which is higher by 5 to 100°c than the melting point of the polyphenylene sulfide resin for at least 30 seconds. It has an increased melt viscosity. 65702-297 PROCESS FOR PRODUCING IMPROVED POLYPHENYLENE SULFIDE RESIN The present invention relates to a process for producing a polyphenylene sulfide resin. In particular, the present invention relates to a process for producing a modified polyphenylene sulfide resin which can be easily molded to form injection-molded products, films, fibers, etc. by increasing the melt viscosity of the polyphenylene sulfide resin. Recently thermoplastic resins having a high heat resistance are required as the materials for components of electric and electronic appliances, - 1 -
