聚苯硫醚因其性能优异和用途广泛 ,目前已成为特种工程塑料的第一大品种 ,位居工程塑料产量第六位。国外聚苯硫醚工业化合成工艺主要是对二氯苯硫化法 ,采用的硫源有硫化钠、硫磺等。国内也开发了不少聚苯硫醚合成工艺 ,但与国外技术相比仍存在很大差距 ,尤其在工程化方面有许 Polyphenylene sulfide because of its excellent performance and wide range of uses, has now become the largest specialty engineering plastics varieties, ranked sixth in engineering plastics production. Foreign industrialization of polyphenylene sulfide synthesis process is mainly dichlorobenzene sulfidation method, the use of sulfur sources are sodium sulfide, sulfur and so on. Domestic also developed a lot of polyphenylene sulfide synthesis process, but compared with foreign technology there is still a big gap, especially in the engineering aspects
