    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.

    摘要： A process is disclosed for producing finely divided, water-insoluble aziridine polymers by polymerisation of aziridines, preferably ethylene imine, in the presence of cross-linking agents which contain at least two functional groups in at least one ether. Also disclosed are modified, water-insoluble aziridine polymers obtained by reacting finely divided, water-insoluble, cross-linked aziridine polymers in an aqueous medium with carbon bisulphide or formaldehyde and a nucleophilic agent from the group of the alkaline metal cyanides, primary amines, secondary amines, alkaline metal sulphites and alkaline metal phosphites. The invention also relates to the use of the modified and non-modified, finely divided, water-insoluble polymers for immobilising active substances, as absorbing agent for aldehydes, ketones and acids and for removing heavy metal ions from waste water.

    摘要： The invention relates to a method for producing paper, paperboard and cardboard by dehydrating paper material containing interfering substances in the presence of fixing agents. Reaction products are used as fixing agents. Said products are obtained by reacting polymers, containing amino and/or ammonium groups, from the group of: polymers containing vinyl amino units, polyalkylene polyamines, polyamidoamines, polyamidoamines grafted with ethylene imine and optionally cross-linked, polydiallydldimethylammoniumchlorides; polymers containing dialkylaminoalkylacrylamide-units or dialkylaminoalkylmethacrylamide units and polyallylamines and dicyandiamide-formaldehyde-condensates, with reactive sizing agents for paper with a polymer/reactive sizing agent weight ratio of 15,000 : 1 to 1 : 1. The invention also relates to reaction products thus obtained and to their use as fixing agents for water soluble and water insoluble interfering substances in the production of paper, paperboard and cardboard from paper materials containing interfering substances.
