Abstract: The invention relates to an associative thickening agent that can be obtained by means of radical polymerization, to the production thereof, and to the use thereof in paper coating colors. The associative thickening agent is formed by (a) acid monomers, selected from ethylene unsaturated C3- to C8-carbolic acids, (b) associative monomers of the general formula H2C=CR1-COO-(EO)n­-(PO)-R2, where R1 is hydrogen or methyl, n is a number greater than or equal to two, m is a number from zero to 50, EO is an ethylene oxide group, PO is a propylene oxide group, and R2 is a C8-C30 or a C8-C30 alkaryl group, and (c) non-ionic copolymerizable monomers different from a) and b), wherein the reaction product has been reacted with initiators forming non-ionic radicals after the polymerization.

Abstract: A paper coating slip additive obtainable by free-radical polymerization, its preparation and its use in paper coating compositions are described. The additive is formed from (a) acid monomers selected from ethylenically unsaturated C3 to C8 carboxylic acids, (b) associative monomers of the general formula H2C=CR1-COO-(EO)n-(PO)m-R2 where R1 is hydrogen or methyl, n is at least two, m is from zero to 50, EO is an ethylene oxide group, PO is a propylene oxide group and R2 is a C8-C30 alkyl group or a C8-C30 alkaryl group, and (c) nonionic copolymerizable monomers other than a) and b), wherein said additive has a weight average molecular weight of below 200 000 and wherein tert-dodecyl mercaptan is used as chain transfer agent.
