Washing- And Cleaning-Active Polymer Films, Process For Their Production And Their Use

A washing- and cleaning-active polymer film, comprising at least one layer obtainable by:

• a) providing an aqueous composition by mixing
• a polymer P1) prepared by free-radical polymerization of a monomer composition M) that comprises at least one monomer A), selected from α,β-ethylenically unsaturated carboxylic acids, salts of α,β-ethylenically unsaturated carboxylic acids and mixtures thereof, wherein the monomer A) is used in an amount of from 50 to 100% by weight, based on the total weight of the monomer composition M),
• a polyoxyalkylene ether PE) having at least one C8-C18-alkyl group that is unsubstituted or substituted by at least one hydroxyl group, and an average of 3 to 25 alkylene oxide units per molecule, and
• water,
• wherein at the most 30 mol % of the carboxy groups of the polymer P1) are in the deprotonated form,
• the weight ratio of the polymer P1) to the polyoxyalkylene ether PE) is in a range from 0.9:1 to 5:1, and
• the aqueous composition has a water content of at least 10% by weight and at most 50% by weight, based on the total weight of the aqueous composition,
• b) converting the aqueous composition to a polymer film.
