Production process of low-corrosive poly (arylene sulfide).

摘要

A process for the production of a low-corrosive poly(arylene sulfide), in which a poly(arylene sulfide) is subjected to an organic acid treatment in a liquid mixture composed of an organic solvent and water in a weight ratio ranging from 4:1 to 1:10, and containing an organic acid in a concentration of 0.1-5.0 wt.%, and the thus-treated poly(arylene sulfide) is then thoroughly washed, is provided. The poly(arylene sulfide) obtained by the process of the invention has high crystallization speed and excellent moulding and processing ability, and exhibits inhibited corrosiveness to metals.
