摘要：
A method for recovering a crystalline poly(arylene sulfide) from a slurry comprising a particulate poly(arylene sulfide), a polar organic compound, and water, said method comprising:(a) substantially liquefying said particulate poly(arylene sulfide) to form a liquid mixture comprising said substantially liquified poly(arylene sulfide) and said polar organic compound;(b) contacting said liquid mixture with a vaporized separation agent in an amount sufficient to effect a separation between said poly(arylene sulfide) and said polar organic compound;(c) reducing the temperature of said liquid mixture sufficiently to solidify said substantially liquified poly(arylene sulfide) to form a slurry comprising a particulate poly(arylene sulfide); and(d) recovering said particulate poly(arylene sulfide) from said slurry.
