Polyfphenylene sulfide

Polyfphenylene sulfide), sold by Phillips Chemical Company under the trade name Rylon, is a highly crystalline aromatic polymer (mp 285°C). It is obtained by the polycondensation of/7-dichlorobenzene and sodium sulfide. The symmetrical arrangement of -substituted benzene rings and sulfur atoms on the polymer backbone permits a high degree of crystallization. This, in addition to the extreme resistance of the benzene ring-sulfur bonds to thermal degradation, confers thermal stability, inherent nonflammability, and chemical resistance on PPS resin.

Whereas some conducting polymers can be processed by synthesis via a soluble precursor, polyfphenylene sulfide) is soluble or can be melt-processed. Doping with AsFj (which can be accelerated by the presence of AsFj) forms a conductive polymer salt with o 1 S cm , but also tends to make the film brittle.

Poly(phenylene sulfide) (PPS) is the thio analogue of polyfphenylene oxide) (PPO) [57]. The first commercial grades were introduced by Phillips Petroleum in 1968 under the trade name Ryton. Other manufacturers also have introduced PPS (e.g., Tedur by Bayer). The commercial process involves the reaction of p-dichlorobenzene with sodium sulfide in a polar solvent.
