Tubular extrusion molding product comprising high molecular weight polyarylene sulfide. |
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 dihaloaromatic 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. |
