This method serves for easy synthesis of fine polymer particles with a narrow particle size distribution and the method can be effectively applied to production of highly heat-resistant polymers that have been difficult to produce with the conventional methods.

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.

The disclosure relates to a high molecular weight polyphenylene sulfide resin and a preparation method and application thereof. The disclosure uses a sulfur-containing compound and a halogenated aromatic compound as raw materials, an alkaline compound and a fatty acid as polycondensation aids to carry out a polycondensation reaction. After purification treatment, a primary polyphenylene sulfide is obtained. Then, the primary polyphenylene sulfide reacts with a chain extender at a high temperature to form a high molecular weight polyphenylene sulfide resin. The preparation method of the disclosure has the advantages of high yield, low cost, and is capable of selectively and controllably preparing polyphenylene sulfide resins with different melt viscosities and molecular weights, and the obtained polyphenylene sulfide resins have excellent heat resistance. The linear high molecular weight polyphenylene sulfide resin with high thermal stability obtained by the disclosure can be used for producing plates, pipes and rods, can be mechanically processed like metals, such as cutting, grinding, polishing, drilling, and can be used to produce fibers, membranes, films, and especially are applicable to automotive parts, electronic/electrical equipment, chemical and machinery industry.

There is provided a reinforcing material equipped with a cohesive/adhesive layer, having a proper initial adhesion force to an adherend, such as an electrolyte membrane, a catalyst layer and a gas diffusion layer, and which can be temporarily fixed readily. A reinforcing material produced by forming a cohesive/adhesive layer on a substrate. The cohesive/adhesive layer includes an aliphatic polyamide, an epoxy resin and a polythiol. When the reinforcing material is used, it becomes possible to correct the position of an adherend after the adhesion of the reinforcing material to the adherend. In addition, it can prevent the formation of wrinkles on the adherend or the like upon the adhesion of the reinforcing material. Therefore, a catalyst layer laminated membrane or the like which has a reinforcing material attached thereto can be produced readily without requiring the employment of any highly skilled technique.
