Abstract

In the presence of diphenyl sulfide, oxygen-oxidative poly-merization of diphenyl disulfide gave highly crystalized poly-(1,4-phenylene sulfide) (PPS) using a vanadyl-strong acid catalytic system. Effect of the sulfide, which was inactive to the vanadyl catalyst, was ascribed to the enhancement of the elec-trophilic substitution with a sulfonium cation onto a thiophenyl end. The finally purified PPS showed high crystallinity (Xc = 44%), which was even higher than that of the reagent grade PPS produced by the conventional polycondensation process.
