摘要

Associative thickener, a process for the preparation of an associative thickener aqueous thickener, composition, the use of an associative thickener, agent of sliding coating of paper, and paper or cardboard. The invention relates to an associative thickening agent which can be obtained P Or polymerization by radical, for the production thereof, and the use of this color to the coating of paper.The associative thickening agent is formed by (a) acidic monomers selected from carboxylic acids (C ~ 3 ~ C ~ 8 ~ etilenicamente unsaturated monomer (b) associations of general formula H ~ 2 ~ C = CR ^ 1 ^ - COO - (EO) ~ n ~ - (PO) - R ~ 2 ~. Where R ^ 1 ^ is hydrogen or methyl, n is a number greater than IGU Al two, M is a number from 0 to 50, EC is a group of ethylene oxide, Po is a group of propylene oxide.And R ^ 2 ^ is a C ~ 8 ~ C ~ 30 ~ or a group alcarila C ~ 8 ~ C ~ 30 ~, and (c) non-ionic monomers copolimerizu00e1veis different (a) and (b), in which the reaction product was reacted with primers which form non ionic radicals after polymerization.
