Abstract

PURPOSE:To obtain the title polymer excellent in melt processability and heat stability, by reacting an alkali metal sulfide with a specified dihaloaromatic compound in an organic amide solvent. CONSTITUTION:An alkali metal sulfide (B) is reacted with a dihaloaromatic compound (C) based on 4,4'-dichloro(or bromo)benzophenone in an organic amide solvent (A) at a reaction temperature of 60-300 deg.C (provided that the period of time during which this temperature is kept at 210 deg.C or above is within 10hr) at a ratio of concomitant water to component A feed of 2.5-15mol./kg and a molar ratio of component C to component B of 0.95-1.2 to obtain a polyarylene thioether ketone mainly consisting of repeating units of the formula (wherein -CO and -S- are para to each other in a benzene ring) and having an m.p. of Tm of 310-380 deg.C, a residual melting/crystallization enthalpy DELTAHmc (420 deg.C/10min) >= 10J/g, and its melting crystallization temperature Tmc (420 deg.C/10min) >= 210 deg.C, and a reduced viscosity of 0.2-2dl/g.
