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.
