A polyarylene having a structural unit shown by the following formula (1) is disclosed.
wherein X and Y indicate a divalent organic group or a single bond, Z shows an oxygen atom or a sulfur atom, R represents at least one atom or group selected from the group consisting of a hydrogen atom, a fluorine atom, an alkyl group, and a fluorine-substituted alkyl group, a is an integer of 1 to 20, n is an integer of 1 to 5, and p is an integer of 1 to 10.
A method for carrying out a chemical reaction between at least two reactants occupying separate phases within a multiphase reaction mixture has been discovered in which at least one phosphazenium salt is employed as a phase transfer catalyst. The remarkable utility of phosphazenium salts as phase transfer catalysts is illustrated by the preparation of aromatic ethers. The phosphazenium salt phase transfer catalysts are shown to be especially useful in the preparation of aromatic polyethers such as polyether sulfones.

A process to form a fiber-reinforced composite having a continuous thermoplastic matrix of poly(arylene sulfide ketone) resins is provided. The composite is useful to form shaped articles with high temperature resistance. The composite can be prepared by consolidating under heating a multi-layer stack of resin sheets and fiber reinforcement sheets. The poly(arylene sulfide ketone) resins can be melt-stabilized through treatment with a water-soluble salt of an alkaline earth metal. The composite has excellent thermal properties such as heat distortion temperature.
