Abstract

Poly(p-phenylene sulfide)s are prepared through the oxidative polymerization of diphenyl disulfides or thiophenol with quinones at room temperature. The formed polymer is isolated as a white and pure powder having a 1,4-conjugated structure. The oxidative polymerization preferentially proceeds through a novel cationic mechanism. Diphenyl disulfide forms a charge-transfer complex with quinones and is oxidized to a sulfonium cation. The cation electrophilically substitutes on the phenyl ring to yield poly(p-phenylene sulfide). Influences of the quinones on this polymerization are discussed in connection with their redox potentials.
