Claim:
A polymer blend, comprising (a) at least one hydrophobic polymer, as component A, selected from the group consisting of: polyamides, homopolyesters and/or copolyesters of aliphatic dicarboxylic acids or aromatic dicarboxylic acids with an apliphatic diol or diol mixture with 2 to 18 C-atoms, polyurethanes, polyolefins, copolymers comprising structural units composed of the abovementioned polymers, and mixtures thereof, (b) at least one hydrophilic polymer, as component B selected from the group consisting of: starch, cellulose, polyvinyl alcohol, proteins, poly(meth)acrylamides, polysaccharides, and mixtures thereof, and (c) at least one structural unit that crosslinks component A and/or B and derives from at least one compound selected from the group consisting of: dialdehydes, diketones, aldehyde ketones, derivatives of the abovementioned compounds, and mixtures thereof, as component C.
