Abstract
PURPOSE: To prepare a poly-p-phenylene sulfide having high molecular weight, high melt viscosity and excellent moldability, by the use of a relatively small amount of an alkaline earth metal fatty acid salt as a polymerization assistant.
CONSTITUTION: The objective polyphenylene sulfide is prepared by reacting (A) a p-dihalogenobenzene or a mixture of a p-dihalogenobenzene and a poly-halogeno- aromatic compound having at least three halogen substitution groups, with (B) an alkali sulfide (except lithium sulfide), in an organic amide solvent, in the presence of (C) an alkaline earth metal fatty acid salt (e.g. calcium acetate) as a polymerization assistant. The molar ratios of (A):(B):(C) are pref. 0.95W1.2:1: 0.10W0.35.
EFFECT: The composition can be easily melt-molded to obtain an article having high chemical resistance, flame-retardancy and heat resistance.
