Abstract
Disclosed are methods of recycling the components of composite articles and materials comprising hydroxy-phenoxyether polymers to facilitate reuse of such components. The recycling methods comprise dissolution of the hydroxy-phenoxyether polymer in an acidic solution which is separated from the other components which formed the composite article or material. The hydroxy-phenoxyether polymers may be reused as the acidic solution, or they may be precipitated by addition of a base prior to reuse.
