Phenylene sulfide polymers. I. Mechanism of the macallum polymerization

Abstract

Abstract The reactions used in the past for the preparation of phenylene sulfide and related polymers are reviewed. The Macallum polymerization is a polycondensation of an aryl halide and an inorganic sulfide or polysulfide in the absence of solvents. The monomer system studied most thoroughly is represented by the following, unbalanced equation:
