    Abstract: A method of preparing an aqueous thickener dispersion from a monomer composition which comprises: (a) at least one ethylenically unsaturated carboxylic acid, and (b) at least one ethylenically unsaturated hydrophobic monomer, where (i) an at least partially polymerized pre-emulsion is prepared from 10 to 80% by weight of the monomer composition and (ii) the remainder of the monomer composition is added in its entirety to the at least partially polymerized pre-emulsion and a free-radical polymerization is initiated using a redox initiator system, wherein the ethylenically unsaturated hydrophobic monomer may be selected from C1-C9-alkyl (meth)acrylates, dienes, vinyl aromatics, (meth)acrylonitrile and mixtures thereof, and the ethylenically unsaturated carboxylic acid may be selected from acrylic acid, methacrylic acid, itaconic acid and maleic acid.

    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.
