PROCESS FOR THE PRODUCTION OF SULFUR-CONTAINING AROMATIC POLYMERS

摘要

A process for the production of a polymer of a sulfur-containing aromatic compound, comprising reacting a halide of a sulfur-containing aromatic compound which bears at least one aromatic ring and at least one ring containing one or more disulfide linkages and in which both rings hold one side in common with inorganic sulfur in an amount of 2 to 8 sulfur atoms per mol of the halide in an organic solvent under heating in the presence of at least one inorganic base selected from the group consisting of alkali metal hydroxides, alkali metal hydrogen- carbonates and alkali metal carbonates and/or at least one organic base selected from the group consisting of tri(lower alkyl)amines and heterocyclic amines.
