    Abstract: (EN) The invention relates to a method for waterproofing lignocellulosic materials by impregnating the lignocellulosic material with a waterproofing agent, whereby the lignocellulosic material is impregnated with a hardenable aqueous composition before or during waterproofing, said composition containing at least one cross-linkable compound, selected from a) low-molecular weight compounds V, having at least two N-bonded groups of formula CH 2 OH, wherein R=hydrogen or C 1 -C 4 alkyl, and/or one 1,2-bis-hydroxyethan-1,2-diyl group, bridging two nitrogen atoms, beta) precondensates of the compound V and & gammad;) reaction products or mixtures of the compound V with at least one alcohol, selected from C 1 -C 6 alkanols, C 2 -C 6 polyols and oligo-C 2 -C 4 -alkylene glycols.

    Abstract: Use of aqueous dispersions comprising at least one at least partially neutralized ethylene copolymer wax selected from among ethylene copolymer waxes which comprise, as comonomers in copolymerized form, (A) from 26.1 to 39% by weight of at least one ethylenically unsaturated carboxylic acid and (B) from 61 to 73.9% by weight of ethylene, and ethylene copolymer waxes which comprise, in copolymerized form, (A') from 20.5 to 38.9% by weight of at least one ethylenically unsaturated carboxylic acid, (B') from 60 to 79.4% by weight of ethylene and (C') from 0.1 to 15% by weight of at least one ethylenically unsaturated carboxylic ester, as auxiliaries for wastewater treatment.

    Abstract: A method for cleaning surfaces using aminoplast foam pieces produced from (a) open-cell aminoplast foams having a density in the range from 5 to 500 kg/m 3 and a mean pore diameter in the range from 1 mum to 1 mm or (b) open-cell aminoplast foams having a density in the range from 5 to 500 kg/m 3 and a mean pore diameter in the range from 1 mum to 1 mm, which have been treated (b1) with an aqueous formulation of at least one compound (b-1) having at least one hemiaminal or aminal group per molecule or at least one copolymer which comprises, incorporated in the form of polymerized units, at least one comonomer containing OH groups or beta-dicarbonyl groups or epoxide groups, or (b2) with at least one polymer (c-1) which is solid at room temperature, contains carboxyl groups and/or carboxylic ester groups and has a molecular weight M n in the range from 1000 to 1 000 000 g/mol, the aminoplast foam pieces used having an average diameter in the range from 0.1 mm to 50 mm.
