The present invention relates to novel polymers P and their salts, to processes for their preparation, to the use of said polymers as dispersants for fine-grained solid materials. The invention further relates to liquid compositions containing fine solid particles such as organic or inorganic pigments or fillers, and containing the novel polymers P and their salts as dispersants. The polymer P has at least one functional group of formula (I), which is bonded to the end of the polymer and/or to the main chain of the polymer: wherein # in the formula (I) represents a bond to the end of the polymer and/or to the main chain of the polymer Point of polymer, variables k, m, A, Q, R 1 , R 2 , X and as defined in claim 1 . |
