Process for preparing polyarylene sulfide with alkali metal salt of phenolic aromatic sulfonic acid |
| abstract |
A process for preparing a polyarylene sulfide which comprises reacting an alkali metal sulfide compound and a polyhalo-substituted aromatic compound in an organic polar solvent in the presence of n (A) an alkali metal salt of a phenolic aromatic sulfonic acid of the formula: n n (HO).sub.m --Ar--(SO.sub.3 M).sub.n n n wherein Ar is a di- to tetravalent aromatic group having 6 to 24 carbon atoms; M is an alkali metal; and m and n are each 1 or 2, n (B) an alkali metal hydroxide and/or an alkali metal alcoholate, and optionally, n (C) an alkali metal salt of sulfuric acid. |
