Abstract: Estructura lineal, planeiforme o tridimensional que contiene, al menos en su superficie, una cantidad que actúa como hidrofilizante de, al menos, un polímero que presenta grupos uretano y/o urea, así como grupos aniónicos, con lo que el contenido de grupos uretano y/o urea asciende, al menos, a 2 mol/kg de polímero, con lo que el polímero presenta una cantidad de grupos aniónicos de 0,5 a 5 mol/kg y con lo que la estructura es provista de polímeros a través del tratamiento de la estructura con una solución disuelta del polímero, con lo que el contenido de polímero de la solución se encuentra en un rango de, al menos, 0,01 a 20 % en peso en relación con el peso de la solución, o para la hidrofilización de las superficies se adiciona el polímero al material del que está compuesta la estructura y a continuación se produce la estructura, y con lo que la estructura es una estructura textil lineal o planeiforme, una lámina plástica o un cuerpo moldeado de plástico.

Abstract: A method is described for producing an aqueous thickener dispersion from a monomer composition made of at least one ethylenically unsaturated carboxylic acid and at least one ethylenically unsaturated hydrophobic monomer, (i) an at least partially polymerized pre-emulsion being produced from 10 to 80 wt.-% of said monomer composition, and (ii) the residual quantity of said monomer composition being added completely to the at least partially polymerized pre-emulsion and initiating a radical polymerization. The monomer composition preferably also comprises an associative monomer. The method avoids disadvantages of batch polymerization, such as inadequate batch-to-batch reproducibility and safety problems.

Abstract: The invention relates to an aqueous dispersion of a copolymer incorporating by polymerization units of a) at least one ethylene unsaturated carbonic acid, b) at least one non-ionic ethylene unsaturated tenside monomer, c) at least one C1-C2-alkylmethacrylate, d) at least one C2-C4-alkylacrylate, the alkyl chain length averaged over the number of alkyl groups of the alkylacrylate being 2.1 to 4Ø After neutralization using alkali, the dispersion serves as an associative thickener, particularly for liquid washing and cleaning agent formulations. The thickeners are characterized by high transparency and high thickening effectiveness at simultaneously high shear dilution.

Abstract: An aqueous dispersion of a copolymer with copolymerized units a) of at least one ethylenically unsaturated carboxylic acid, b) of at least one nonionic ethylenically unsaturated surfactant monomer, c) of at least one C1-C2-alkyl methacrylate, d) of at least one C2-C4-alkyl acrylate, where the alkyl chain length averaged over the number of alkyl groups of the alkyl acrylate is 2.1 to 4.0, is described. Following neutralization with alkali, the dispersion serves as associative thickener, in particular for liquid detergent and cleaner formulations. The thickeners are characterized by high transparency and high thickening effect coupled with high shear dilution.
