<p>Process for the manufacture of poly(arylene sulphide), consisting in polymerising in one stage a reaction mixture including the following constituents: - an alkali metal sulphide (a); - a polar organic solvent (b); - an alkali metal carboxylate (c); - water (d); - a dihalogenated aromatic compound (e), characterised by the combination, in the said mixture, of a molar ratio (RH2O) of water (d) to the sulphide (a) used, such that: 2.6 </= RH2O </= 3.8 and of a molar ratio (RADD) of the carboxylate (c) to the sulphide (a) used, such that: 0.20 </= RADD </= 0.90</p> |
