Abstract
This invention pertains to cross-linked hydrophilic polymeric films, the process of making such films, and their use. The films of this invention are produced by solubilizing a water-soluble polymer with a photosensitive or light degradable catalyst, optionally drying said solution, and exposing the solution to an energy source, particularly light. These films are suitable for use as a carrier for biologically active agents, such as pharmaceuticals, both human and veterinary, insecticides, and fertilizers; as hydrophilic membranes for separation processes; as bandages for wound treatment; as body implants or as coatings for such implants; and as coatings on glass, metal, wood or ceramics.
