    Abstract: The present invention relates to a method for producing water-soluble films, wherein the water-soluble film comprises at least one layer S1) containing or consisting of a polymer composition P1), obtainable by free-radical polymerization of a monomer composition M1) which contains at least one monomer A) selected from a,ß-ethylenically unsaturated mono-and dicarboxylic acids, salts of a,ß-ethylenically unsaturated mono-and dicarboxylic acids, anhydrides, a,ß--ethylenically unsaturated mono-and dicarboxylic acids, and mixtures thereof, in the presence of at least one polyether component PE), which is selected from polyetherols having a number average molecular weight of at least 200 g/mol, mono-and di-(C1-C6-alkyl) ethers of such polyetherols, polyether groups-containing surfactants and mixtures thereof, wherein the film can have further layers, and wherein the layers are cast on a support material.
