A process is provided to recover poly(arylene) sulfide from a poly(arylene) sulfide reaction mixture. In particular, a process is provided to recover poly(arylene) sulfide utilizing at least one extraction agent followed by vacuum drying.

Processes for the recovery of poly(arylene sulfide)

A novel treatment and recovery process is provided which produces commercially desirable high molecular weight poly(arylene sulfide)s from undesirable low molecular weight poly(arylene sulfide)s. The novel process reduces the quantity of low molecular weight poly(arylene sulfide)s which otherwise have little or no commercial value and can require disposal.

A process is provided for moving at least one contaminant selected from the group consisting of phenol thiophenol, and phenyl disulfide from contaminated NMP by reacting at least one monohalogenated aromatic compound and a base with the contaminate NMP.

Removal of contaminants from N-methyl-2-pyrrolidone

A process is provided for producing a high molecular weight poly(arylene sulfide) polymer employing at least one dihaloaromatic compound, a sulfur source, a polar organic compound, a lithium salt which is soluble in the polar organic compound, and water in an amount less than about 1.75 moles of water per mole of sulfur under polymerization conditions. The pressure and temperature are chosen to allow the volatile reactants to be maintained in liquid form in the reaction mixture.

Process for preparing high molecular weight poly(arylene sulfide)

A process is provided for producing a poly(arylene sulfide) polymer which employs at least one base as a reactant, wherein the base is contacted with the polymerization reaction mixture incrementally during the polymerization.

Process for preparing poly(arylene sulfide) polymers

Poly(arylene sulfide) fibrid particles and process for their preparation

A process is provided for producing a poly(arylene sulfide) polymer which employs as a reactant cyclic arylene sulfide oligomers.

Process for preparing poly(arylene sulfide) polymers using cyclic

A method is provided for selectively extracting the lower molecular weight fraction of a poly(arylene sulfide) polymer by contacting the polymer with a polar organic compound and a promoter compound to form a less dense polymer-lean liquid phase and a more dense polymer-rich liquid phase, separating the polymer-lean liquid phase from the polymer-rich liquid phase, and recovering the polymer from the polymer-rich phase. Alternatively, either of the phases can be isolated and polar organic compound and optionally promoter can be added to form two new phases, followed by isolation of the new polymer-rich phase. This process can be repeated as often as desired or practicable in order to recover polymer having a desired molecular weight and/or molecular weight distribution.

A poly(arylene sulfide ketone) or poly(arylene sulfide diketone) resin having improved handling characteristics is prepared by a process comprising preparing in a first enclosed vessel a slurry comprising a solid poly(arylene sulfide ketone) or poly(arylene sulfide diketone) resin and a liquid polar organic compound, and optionally water; then substantially liquifying the resin to form a mixture comprising substantially liquified resin and polar organic compound; then flashing the mixture into a second vessel having a pressure lower than the first vessel, thereby removing a portion of the polar organic compound and solidifying the resin. When the slurry further comprises water, the invention method optionally includes a venting step prior to the substantial liquification of the resin and/or a concentration step after the substantial liquification of the resin.
