Abstract
This invention deals with a tissue protecting, spray-on film composition comprising an amphiphilic film-forming, segmented/block copolymer derived form at least one water-soluble monomer and at least another water-insoluble monomer, wherein the film can be formed from a water soluble organic solvent such as 2-propanol, acetone, and ethyl acetate. The film can contain a bioactive agent including those to have antimicrobial, anesthetic, anti-inflammatory, and wound-healing activities.
Claims12
A tissue protecting, spray-on film composition consisting essentially of an amphiphilic, segmented/block copolymer having A-B diblock chain structure, wherein the A-block is derived from at least one water-insoluble monomer comprising an alkyl methacrylate, and wherein the B-block is derived from at least one water-soluble monomer comprising N-vinyl pyrrolidone, wherein said copolymer has a molecular weight of at least 15 kDa and is dissolved in at least one water soluble solvent selected from the group consisting of ethyl acetate:
- ethanol, 2-propanol, and acetone.
