摘要： A method of producing a glass fiber-reinforced recycled PPS resin composition, includes: crushing a molded product containing a polyphenylene sulfide resin and glass fibers to obtain a crushed molded product (A), and mixing the crushed molded product (A) and a PPS resin composition (B) containing 40 to 90 wt % of the PPS resin having a weight average molecular weight of 20,000 to 60,000 and 10 to 60 wt % of glass fibers. The glass fiber-reinforced recycled PPS resin composition suppresses breakage of glass fibers at the time of recycling the glass fiber-reinforced PPS resin composition, and has excellent mechanical properties.
