Abstract

PURPOSE: To improve the yield and polymerization degree of the title polymer, by using a solvent containing 1,3-dimethyl-2-imidazolidinone.
CONSTITUTION: (A) One mole of an aromatic polyhalogenated compound, e.g. 1,4- dichlorobenzene, is reacted with (B) 0.6W1.2 moles of an alkali sulfide, e.g. lithium sulfide, or (C) 0.8W1.2 moles of an alkali hydrosulfide, e.g. sodium hydrosulfide, in a solvent, e.g. methyl-2-imidazolidinone, or a mixture of 40W10vol% of N- methylpyrrolidone, and the solvent is evaporated and removed to give the desired phenylene sulfide polymer. The solvent is used in an amount of 300W800g per mole of the alkali sulfide or hydrosulfide.
EFFECT: Little loss of solvent and a short time for its recovery.
