摘要： A method is provided for recovering poly(arylene sulfide) from a liquid reaction mixture, comprising a liquid-phase poly(arylene sulfide) and a polar organic compound which can also function as a solvent for the polymer, and water. The liquid reaction mixture is contacted by an amount of a vaporized phase separation agent at least sufficient to effect or enhance a phase separation of the liquid-phase poly(arylene sulfide) component from the polar organic compound. The poly(arylene sulfide resins recovered according to this invention exhibit greater particle size than those recovered according to prior art methods, and do not tend to adhere to vessel walls during recovery.

摘要： In one embodiment, a process is provided for treating virgin arylene sulfide resins, wherein a heated polymer slurry, comprising a virgin arylene sulfide resin and water, is contacted by a buffer solution having a pH less than about 9.35 but greater than that necessary to result in at least a partial curing of the virgin arylene sulfide resin. In a further embodiment, a process is provided for treating a virgin arylene sulfide resin, wherein a virgin arylene sulfide resin is slurried in a buffer solution having a pH less than about 9.35 but greater than that necessary to result in at least a partial curing of the virgin arylene sulfide resin. The treating process of this invention is conducted at an elevated temperature, below the melting point of the virgin arylene sulfide resin, while in the substantial absence of a gaseous oxidizing atmosphere. The treated arylene sulfide resins are recovered from the polymer slurry in a manner which does not result in at least a partial curing of the treated resin.
