    摘要: The present application relates reinforced poly(arylene sulfide) compositions and processes of producing the reinforced poly(arylene sulfide) compositions. The reinforced poly(arylene sulfide compositions can be prepared by blending the reinforcing agent with the poly(arylene sulfide) or by including the reinforcing agent in the process to produce the poly(arylene sulfide). Reinforcing agents which can be utilized are graphenes (e.g., single-walled carbon nanotubes). The inclusion of the graphene reinforcing agent in the poly(arylene sulfide) composition affects the crystallization properties and/or the conductivity of the melt processed poly(arylene sulfide) compositions.

    摘要: 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.

    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.
