    摘要： The present invention relates to a PPS resin composition comprising a matrix of the PPS which is filled with a PTFE powder baked at a temperature not less than a melting point thereof and having a number-average molecular weight of not less than 1.5 million or PTFE fine particles having an average particle size of 0.05 to 1 .mu.m and comprising a fibrillating core portion of a high molecular weight PTFE with a number-average molecular weight of not less than 1.5 million and a non-fibrillating shell portion of a low molecular weight PTFE so that a content thereof is 40 to 80% by weight in the composition, and also relates to a process for preparing said PPS resin composition, which is characterized in that melting and kneading are carried out at a temperature from a temperature of not less than a melting point of PPS to a temperature of not more lower than a melting point of a high molecular weight PTFE. The polyphenylene sulfide resin composition of the present invention presents sliding properties such as excellent friction and wear resistance which sliding materials mainly containing usual polytetrafluoroethylene have as well as properties of polyphenylene sulfide such as injection moldability and high mechanical properties.
