    Abstract: The use of polymers (I) as biocides is new, where (I) comprises: (a) 0.1-100 mol. % vinylamine (VA) or ethyleneimine units; (b) 0-99.9 mol.% units derived from at least one monomer selected from N-vinylcarboxamides of formula CH2=CH-N(R1)-CO-R2 (II), vinyl formate, vinyl acetate, vinyl propionate, vinyl alcohol, (1-6C) alkyl-vinyl ethers, monoethylenically unsaturated 3-8C carboxylic acids, or their esters, nitriles, amides and anhydrides, N-vinylurea, N-vinylimidazoles and N-vinylimidazolines; and (c) 0-5 mol.% units derived from monomers with at least two ethylenically unsaturated double bonds. The sum of (a)-(c) is 100 mol.%. R1, R2 = H or 1-6C alkyl.

    Abstract: A process for the production of stable water-in-oil emulsions of hydrolysed polymers of n-vinyl amide of formula (I) in which R, R1 = H or C1-C6 alkyl, by the polymerisation of compounds of formula (I) alone or mixed with other ethylenically unsaturated monomers in the presence of polymerisation initiators and emulsifiers in the form of water-in-oil emulsions to form waterin-oil polymer emulsions followed by the hydrolysis of the polymers in the form of the water-in-oil polymer emulsions in the presence of acids or bases and 1 to 30 wt % in relation to the polymers of emulsifiers, in which the emulsifiers used are mixtures of (a) 5 to 95 wt % of a block or graft copolymer of the structure (A-B)m, (A)nB or (B)nA in which A is a hydrophobic homo or copolymer with a degree of polymerisation of at least 3, B is a hydrophilic homo or copolymer with a degree of polymerisation of at least 3, m >= 1 and n >= 2, and (b) 5 to 95 wt % of another water-in-oil emulsifier with a molar mass of under 1000 g/mol. The polymer emulsions thus obtained may be used as retention and flocculation agents in paper production, to purify waste water and sludges in purification plants, as a dispersant and protective colloid for drilling muds and as a cement additive.

    Abstract: Insoluble, only slightly swellable polymers containing amino groups, which can be obtained from popcorn polymers containing units of the structure (I) where R and R1 are H or C1-C4-alkyl, by eliminating the group R-CO- from at least 2% of the incorporated units of the structure I, with the formation of units of the structure II (II), a process for the preparation of the amino-containing popcorn polymers by polymerizing N-vinylcarboxamides and, if desired, other monoethylenically unsaturated monomers copolymerizable therewith with from 0.1 to 10% by weight, based on the monomers used in the polymerization, of a compound containing at least two ethylenically unsaturated non-conjugated double bonds as crosslinking agent, with exclusion of oxygen and polymerization initiators, to form popcorn polymers, and elimination of formyl groups from at least 2% of the copolymerized N-vinylcarboxamides, and the use of the resulting insoluble, only slightly swellable polymers containing amino groups as ion exchangers or adsorber resins for metal ions are described.
