摘要 |
The invention concerns the use as biocides of polymers which contain the following incorporated by polymerization: (a) between 0.1 and 100 mol % vinyl amine units or ethylene imine units; (b) between 0 and 99.9 mol % units of at least one monomer selected from the group comprising open-chain N-vinyl carboxylic acid amides, vinyl formiate, vinyl acetate, vinyl propionate, vinyl alcohol, C1 to C6 alkyl vinyl ether, monoethylenically unsaturated C3 to C8 carboxylic acids, their esters, nitriles, amides and anhydrides, N-vinyl urea, N-vinyl imidazoles and N-vinyl imidazolines; and (c) between 0 and 5 mol % units of monomers having at least two ethylenically unsaturated double bonds. The total of (a), (b) and (c) in mol % is always 100.
