Abstract
Abstract Polymer compositions and methods of making them are provided. Selected surface layers of the polymers, integral with the polymer body, possess pressure sensitive adhesive properties. The polymers are cured with the selected surfaces in contact with a cross-linking inhibition agent which controls the amount of cross-linking of the polymer taking place at the surface. The polymers are useful as, or in conjunction with, prosthetic appliances which are adhered to skin or other substrates.
