ABSTRACT OF THE DISCLOSURE A film forming, spray applicable polymeric solution for production of a wound dressing, characterized in that it consists from the solution of an interpolymer dissolved in a volatile organic solvent, the interpolymer consisting of (a) 10 to 30 wt.% (relative to total weight of monomers) isobutene; (b) 5 to 85 wt.% (relative to total weight of monomers) of one or more esters of acrylic or methacrylic acid with non-branched or branched, primary or secondary aliphatic alcohols with 1 to 4 carbon atoms or their mixtures, and (c) 5 - 85% (relative to total weight of monomers) of one or more maleic acid moloalkylesters with 1 to 12 carbon atoms in alkyl, wherein the one or more maleic acid monoalkylesters can be totally or partially substituted by .alpha.,.beta.-unsaturated mono- carboxylic acids such as acrylic or methacrylic acid, by basic monomeric units or their mixtures containing amino groups, or - in a proportion of up to 75 wt.% of the maleic acid monoester portions - by fumaric acid dialkylester with 1 to 6 carbon atoms in alkyl. The solution of the interpolymer is filled in an aerosol container together with a propellant agent.
