A process is provided to recover at least one modifier compound and at least one polar organic compound from a poly(arylene sulfide) reaction mixture comprising high molecular weight poly(arylene sulfide), low molecular weight poly(arylene sulfide), cyclic and linear poly(arylene sulfide) oligomers, at least one polar organic compound, at least one modifier compound, and an alkali metal halide by-product.

Menthanol extraction of polar organic compounds and modifier compounds from poly(arylene sulfide) polymer and oligomer streams

A process is provided to recover at least one modifier compound and at least one polar organic compound from a reaction mixture comprising high molecular weight Poly(arylene sulfide) product, low molecular weight P(AS), cyclic and linear P(AS) oligomers, at least one POC, at least one modifier, an alkali metal halide by-product, and water.

Process for producing poly(arylene sulfide)

A method for producing particles having a controlled particle size from agglomerated material is provided. Agglomerated material is passed through a beater mill and subjected simultaneously to the beating action of a plurality of blades and a vigorous stream of air as the agglomerated material impacts the peripheral screen of the beater mill. Catalyst or catalyst support particles having a readily controlled particle size and pore volume as well as narrow particle size distribution, are obtained as a result of the invention particulation method
