  • Publication number: 20130317159
    Abstract: 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.

  • Patent number: 8263734
    Abstract: The techniques provide a system and a method of producing polyphenylene sulfide (PPS) polymer. The PPS polymer is produced by reacting a sulfur source and a dihaloaromatic compound in the presence of a polar organic compound in a polymerization mixture in a polymerization vessel. The PPS polymer is washed with a base to lower the oligomer content of the PPS polymer and thus the off-gassing during processing.

  • Patent number: 6946540
    Abstract: Disclosed herein is a process for preparing cured arylene sulfide polymers. A first curing vessel comprising a first agitator is used to cure a poly(arylene sulfide) compacted powder. The curing proceeds until the compacted powder reaches a melt flow rate within a target range. When the melt flow rate of the compacted powder first reaches the target range, the power consumption of the first agitator is determined. A second curing vessel comprising a second agitator is charged with a second quantity of the compacted poly(arylene sulfide) powder. The second quantity of compacted powder is cured in the second vessel until the power consumption of the second agitator reaches the value at which the melt flow rate in the first curing vessel first reached the target range.

  • Patent number: 6562238
    Abstract: In a multistage counter current wash operation wherein an original solvent contained in a cake of polymeric material is displaced with a wash solvent which enters the final stage and progresses forwardly a mathematical model of the counter current wash operation is developed for providing a feedforward control system. In use, the feedforward control system maintains a desired weight fraction of the original solvent that remains in the cake exiting the final wash stage at a desired low level by manipulating the wash solvent flow rate as a function of the flow rate of the feed material. Additionally a feedback control is used in conjunction with the feedforward control.
