Abstract
Abstract Copolymer films are used in place of surgical sutures. When applied to the live skin these copolymer films not only protect skin wounds and injuries but also take the place of traditional stitching of wounds at the end of surgical operations, aid healing and eliminate scars. The copolymers may be applied in liquid form by a dropper or syringe or may be applied on the skin as an aerosol.

Claim 6
Independent Claim
163 words
A method for the elimination of scars in the healing of a sutured wound, consisting of: surgically eliminating scar cells leaving edges of normal skin tissues; bringing said edges of normal skin tissues together; applying a composition on and about said edges of normal skin tissues comprising an inert solvent and a synthetic resin copolymer composition consisting essentially of up to 99 percent by weight vinyl chloride, up to 50 percent by weight vinyl acetate, and 0 to 20 by weight maleic acid; and vaporizing said solvent whereby a continuous synthetic resin film selected from the group consisting of interpolymers of vinyl chloride, vinyl acetate and maleic acid, copolymers of vinyl chloride and vinyl acetate, Mixtures of polyvinyl chloride and said interpolymers, mixtures of polyvinyl acetate and said interpolymers, mixtures of polyvinyl chloride and said copolymers, and mixtures of polyvinyl acetate and said copolymers, is formed which adheres tightly to said skin tissues surrounding said wound but does not enter said wound itself.
Claim 7
Independent Claim
