Abstract: The invention relates to water-soluble, hydrophobically associating copolymers containing novel hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether group with a block structure consisting of a hydrophilic polyalkylene oxide block, which essentially consists of ethylene oxide groups, and of a terminal, hydrophobic polyalkylene oxide block, which consists of alkylene oxides with at least 4 and preferably at least 5 carbon atoms.

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: Se describe un método para producir una dispersión acuosa del espesante a partir de una composición monomérica hecha de por lo menos un ácido carboxilico con insaturación etilénica y por lo menos un monómero hidrofóbico con insaturación etilénica, (i) una pre-emulsión al menos parcialmente polimerizada siendo producida desde 10 hasta 80% en peso de la composición monomérica, y (ii) la cantidad residual de la composición monomérica siendo adicionada completamente a la pre-emulsión al menos parcialmente polimerizada e iniciando una polimerización por radicales. La composición monomérica preferiblemente también contiene un monómero asociativo. El método evita las desventajas de polimerización por lote, como puede ser la inadecuada reproducibilidad lote a lote y problemas de seguridad.
