Abstract

See full text

A method of forming a polymer matrix composite using a soluble derivative of a poly (aryl ether ketone) (PAEK). The method includes mixing a starting PAEK polymer with a solvent and an acid, said solvent being selected from a group consisting of diethylether, tetrahydrofuran (THF), dioxin, and chlorinated solvents; reacting 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; and impregnating a plurality of fibers in a solution comprising said poly (aryl ether thioacetal) compound.
