ABSTRACT:
Methods of impregnating various polymer substrates with an impregnation additive, by simultaneously contacting the polymer substrate with an impregnation additive, carrier liquid, and supercritical fluid are provided. The impregnation additive is substantially insoluble in the supercritical fluid, and the carrier liquid is preferably substantially insoluble in the supercritical fluid.
