Abstract: Aqueous binding agent (A) comprises: (1) a polymer or its mixture obtained by radical polymerization of 5-100 wt.% of ethylenic unsaturated compound, ethylenic unsaturated carbonic acid, dicarbonic acid and/or dicarbonic acid anhydride (which together are called acid monomers); (2) alkanolamine with at least two hydroxyl groups; and (3) a yellowing inhibitor. An independent claim is included for the controlled crosslinking of the aqueous bonding agent comprising: crosslinking the polymer and alkanolamine by increasing the temperature and determining the yellowing tone of the obtained product; determining the quantity of yellowing inhibitor necessary to compensate the yellowing tone and adding the determined quantity to (A); and subsequently crosslinking (A) by increasing the temperature, where the duration of the crosslinking reaction is controlled by coloring the crosslinking product.

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.

Abstract: The present invention relates to the use of formaldehyde-free aqueous binders having a broad molecular weight distribution for substrates, said binders comprising (A) from 0 to 100% by weight of an ethylenically unsaturated acid anhydride or ethylenically unsaturated dicarboxylic acid whose carboxylic acid groups can form an anhydride group, or mixtures thereof, (B) from 100 to 0% by weight of an ethylenically unsaturated compound, (C) at least one polyfunctional crosslinker or mixtures thereof, and (D) from 1-80% by weight of an aqueous polymer dispersion, the polymers of A) and B) obtained by free-radical addition polymerization, when classified in a coordinate system by way of their average molecular weight Mw and their polydispersity, being situated in the area above a straight line which is defined by the linear equation y=1.25x+20 000 and has been shifted in y direction parallelwise by at least +3 000, the x axis denoting the weight-average molecular weight and the y axis the polydispersity times 10 000. The invention further relates to the binders themselves and also to their use for, for example, moldings, mats or boards, especially for fibrous and particulate substrates such as fiber webs, glass fibers, rockwool, reclaimed cotton, natural fibers or synthetic fibers.

Abstract: The invention relates to copolymers which contain alkylene oxide units and also contain the following constituents that are incorporated by polymerization in a statistical or block-by-block manner: (a) 50 to 93 mol % of acrylic acid and/or of a water-soluble salt of the acrylic acid; (b) 5 to 30 mol % of methacrylic acid and/or of a water-soluble salt of the methacryl ic acid, and; (c) 2 to 20 mol % of at least one non-ionic monomer of formula (II), in which the variables have the following meanings: R1 represents hydrogen or methyl; R2 represents a chemical bond or unbranched or branched C1- C6 alkylene; R3 represents identical or different unbranched or branched C2- C4 alkylene groups; R4 represents unbranched or branched C1-C6 alkyl, and; n ranges from 3 to 50. These copolymers are used as an additive in detergents and cleansers.
