Abstract

A washing- and cleaning-active polymer film is disclosed. The washing- and cleaning-active polymer film includes a polymer composition obtainable by a free-radical polymerization of a monomer composition. The monomer composition includes at least one α,β-ethylenically unsaturated carboxylic acid or acid salt. The monomer composition is subjected to a free-radical polymerization in the presence of at least one polyether component. A process for producing the washing- and cleaning-active polymer film is further disclosed. A use of the polymer film and a covering or coating for a detergent or cleaner portion including the polymer film is disclosed.
