    摘要： A tubular extrusion molding product comprising a high molecular weight polyarylene sulfide having a melt viscosity of from 3,100 poise to 60,000 poise produced by reacting an alkali metal sulfide and a dihaloaromtic compound in the presence of an organic amide solvent, cooling a gaseous phase part in the reaction zone during the reaction thereby condensating at least a part of the gaseous phase and refluxing the resultant condensate to a liquid phase in the reaction zone. A tubular extrusion molding product having further improved impact resistance can be provided by copolymerizing from 0.2 mol % to 1 mol % of a polyhaloaromatic compound to the alkali metal sulfide. A tubular extrusion molding product of improved impact resistance is provided by further applying a heat treatment of the polyarylene sulfide intermediate product thereby increasing the melt viscosity.

    摘要： In the preparation of polyarylene sulfide (PAS) by reacting an alkali metal sulfide with a dihaloaromatic compound in an organic amide solvent to obtain a polyarylene sulfide slurry and subjecting the slurry to acid treatment, an acid or hydrogen salt is added to the slurry in such an amount that a pH of the slurry is more than 7.0 and at most 11.0 to carry out the acid treatment. Alternatively, a zinc compound in an amount of 0.1 to 1.5 mole % per mole of the alkali metal sulfide supplied is added to the polyarylene sulfide slurry to treat the slurry, and, then, an acid or hydrogen salt in an amount of at least 0.2 mole % per mole of the alkali metal sulfide supplied is added. The PAS thus obtained has high crystallization speed, high whiteness, high mechanical strength and high melt viscosity, V6.
