Abstract

PURPOSE:To obtain a high-MW polymer in high yields, by polymerizing 4,4'- dimercaptodiphenyl sulfide with a 4,4'-dihalodiphenyl sulfide in a solvent in the presence of an alkali (bi) carbonate. CONSTITUTION:A polyphenylene sulfide of the formula is obtained by polymerizing 4,4'-dimercaptodiphenyl sulfide with a 4,4'-dihalodiphenyl sulfide by keeping them at 200-400 deg.C in a solvent in the presence of an alkali carbonate or an alkali bicarbonate. Examples of said 4,4'-dihalodiphenyl sulfides used include 4,4'-dichlorodiphenyl sulfide and 4,4'-dibromodiphenyl sulfide. Good results can be usually brought about when the molar ratio between the materials is such that 4,4'-dimercaptodiphenyl sulfide is used in an amount which is slightly excess over an equimolar amount and is in the range of 1.00-1.2mol.
