pps pps is a thermoplastic engineering plastic containing benzyl sulfide on the main chain of the molecule, which is a polyether. it was industrialized in the united states in 1968. the main methods of production in the industry were solution polymerization&self condensation. the molecular structure of pps can be seen, it is in the benzene&sulfur s co-ed of alternately arranged linear/slightly branched polymer, the molecular chain of regulatory integrity, connected by a rigid ring with flexible thioether chain has a primary key features so pps can move among force&soft, crystalline, high melting point; secondly, because the benzene&sulfur s conjugate formation.&the sulfur is not in saturation, after oxidation the thioether bond into sulfoxide group,/the adjacent molecules to form oxygen bridge branched/crosslinked, the heat&oxygen stability is outstanding; third, due to the polar sulfur s are conjugated&bound with high crystallinity, the
