Continuous Fiber Reinforced Polyarylene Sulfide

Номер: US20130273280A1
Автор: Aaron Johnson, David Eastep, Rong LUO, Tim TIBOR, Xinyu Zhao
Принадлежит: Ticona LLC

A continuous fiber composite is described and methods for forming the continuous fiber composite. The continuous fiber composite includes a plurality of unidirectionally aligned continuous fibers embedded within a polyarylene sulfide polymer. The continuous fiber composite includes a very high loading of continuous fibers, for instance greater than about 40% by weight of the continuous fiber composite. The continuous fiber composite is formed by reacting a starting polyarylene sulfide with a reactively functionalized disulfide compound in a melt processing unit. Reaction between the starting polyarylene sulfide and the reactively functionalized disulfide compound leads to formation of a reactively functionalized polyarylene sulfide. Upon embedding of the continuous fibers into the reactively functionalized polyarylene sulfide, the reactivity of the polyarylene sulfide can enhance adhesion between the polyarylene sulfide polymer and the fibers.

Fluorinated surfactants and stabilization of polytetrafluoroethylene (ptfe) particles in hollow fiber spin solutions

Номер: US20140096682A1
Автор: Clint P. AICHELE, Imona C. Omole
Принадлежит: Phillips 66 Co

Methods and apparatus relate to recovery of carbon dioxide and/or hydrogen sulfide from a gas mixture. Separating of the carbon dioxide, for example, from the gas mixture utilizes a liquid sorbent for the carbon dioxide. The liquid sorbent contacts the gas mixture for transfer of the carbon dioxide from the gas mixture to the liquid sorbent. Contacting of the sorbent with the gas mixture and/or desorption of the carbon dioxide from the liquid sorbent utilize hollow fiber contactors that have permeable walls and incorporate particles distinct from a remainder of the walls to influence wetting properties of the contactors. Polytetrafluoroethylene particles may be homogenously disposed throughout hollow fiber contactors to influence wetting properties of the contactors.

The embodiments of the present disclosure present systems and methods for the reversible solubilization of (aryl ether ketones) (PAEKs). A thioacetalization process is employed to modify the PAEKs into poly (aryl ether thioacetals) which, unlike PAEKs, are substantially soluble in common solvents. This modification allowing selected analysis techniques to be more easily performed on PAEKs, such as gel permeation chromatography. The thioacetalization may be reversed through a deprotection reaction to recover the original PAEK without substantial degradation, allowing for non-destructive characterization of the PAEK. Advantageously, the thioacetalization process is generally applicable to a broad range of PAEKs, unlike presently known methods of solubilizing PAEKs. Solubilization of PAEKs further expands the utility of the PAEKs, opening up additional routes to chemical modification of PAEKs, as well as allowing for the possibility of processing PAEKs from solution. 1. A method of forming a soluble derivative of a poly (aryl ether ketone) (“PAEK”) , comprising:mixing a starting poly (aryl ether ketone) (PAEK) polymer with a solvent and an acid, said solvent being selected from a group consisting of diethylether, tetrahydrofuran (THF), dioxin, and chlorinated solvents; andreacting the PAEK mixture with a Lewis acid and a thiol compound in amounts effective to form a poly (aryl ether thioacetal) compound which comprises at least one thioacetal group;{'sub': 3', '2, 'wherein the Lewis acid is boron trifluoride diethyl etherate (BFEtO), the thiol compound is 1,2 ethanedithiol or 1,3-propanedithiol, and the starting PAEK is selected from: poly (ether ketone) (“PEK”), poly (ether ether ketone) (“PEEK”), poly (ether ketone ketone) (“PEKK”), and poly (ether ketone ether ketone ketone) (“PEKEKK”).'}2.
