ABSTRACT:
A process for producing a polyarylene ester, which comprises subjecting to a polymerization reaction a slurry of at least one divalent phenol, at least one aromatic carboxyl dichloride and calcium hydroxide (in the form of solid particles), the calcium hydroxide being used in an amount of at least 1.5 mol to one mol of the divalent phenol, in an inert organic liquid which is a solvent for the polyarylene ester but not a solvent for calcium hydro-oxide to give a reaction mixture consisting of a solid phase and a single liquid phase containing the polyarylene ester dissolved in the inert organic liquid, and then separating the liquid phase from the solid phase.
