    摘要: The present invention pertains to a process for the production of an article comprising a polymer itself comprising poly(phenylene sulfide), which process comprises:A. contacting poly(phenylene sulfide) with at least one organic compound, consisting essentially of carbon and hydrogen, and optionally oxygen, nitrogen, sulfur, halogen, or mixtures thereof, having a molecular weight of between about 110 and 450 daltons and having at least one six membered aromatic ring structure, which compound is stable at a temperature of between 160.degree. and 400.degree. C. at ambient pressure, at a temperature of between about 160.degree. and 400.degree. C. at ambient pressure for a time effective to dissolve greater than 10 percent by weight of the poly(phenylene sulfide) present, with the proviso that when oxygen is present, the organic compound is not diphenyl oxide or substituted diphenyl oxide;B. forming the solution of poly(phenylene sulfide) and solvent of Step (A) into a desired article configuration;C. removing the solvent; andD. recovering the article comprising poly(phenylene sulfide) formed thereby. The article is particularly useful when it is in the shape of a thin membrane, hollow fiber or solid fiber and is porous, permeable, semi-permeable or selectively permeable.

    摘要: High-quality polyarylene-thioether fibers are provided, which simultaneously satisfy the following conditions:(a) the polyarylene-thioether is a linear polyarylene-thioether having a melt viscosity of 5,300 to 20,000 poise (at 310.degree. C. and a shear velocity of 200 second.sup.-1);(b) the fiber diameter is in the range of 1 to 50 microns;(c) the tensile strength is not less than 40 kg/sq.mm;(d) the tensile modulus of elasticity is not less than 500 kg/sq.mm; and(e) the tensile strength at 200.degree. C. is not less than 20 kg/sq.mm.The fibers are produced by continuously melt-spinning a linear polyarylene-thioether polymer having a melt viscosity of 5,300 to 20,000 poise (at 310.degree. C. and a shear velocity of 200 second.sup.-1), continuously stretching the spun filament, and continuously heat-setting the stretched filament for 0.02 to 100 seconds at a temperature of not lower than the melting point of the polymer minus 100.degree. C.
