The physical and chemical properties of polyphenylene sulfide （PPS） were introduced. The synthesis technologies of PPS were analyzed, including sodium sulfide route, sulfur solution route, hydrogen sulfide route, halogenated thiophenol pely- condensation and oxidation polymerization. The application development of PPS was described. The research of the formation and processing technology of PPS was described in details. Owing to its excellent thermal stability, chemical resistance and flame re- tardancy, PPS was widely used in the fields of environment protection, electronics, mechanics, automobile, textile and aero- space. It was put forward that the research in the synthesis and processing of high-performance PPS should be accelerated and the spinning technology research and industrial application of PPS fiber should be enhanced.
