Abstract
PURPOSE: The reaction between p-dihalobenzene and alkali sulfide is conducted in an organic amide solvent in the presence of an alkali salt of organic sulfonate to produce title composition having high polymerization degree and being melt moldable.
CONSTITUTION: The reaction of p-dihalobenzene with alkali sulfide except lithium sulfide is carried out in an oarganic amide solvent in the presence of at least one of aromatic sulfonate alkali metal salts of formula I and II (R is 1W12C alkyl, n is 0W2, M is Na, K, Rb, Cs) to produce high-viscosity poly-p-phenylene sulfied. The p-dihalobenzene used is preferably p-dichlorobenzene and the molar ratio of the p- dihalobenzene to the alkali sulfide is 0.95:1W1.2:1. The molar ratio of the aromatic sulfonate alkali metal salt added to the alkali sulfide is 0.1W1.5.
