    Abstract: The present invention relates to novel polymers P and to their salts, to a process for their manufacturing, to the use of said polymers as dispersants for fine particulate solid material. The present invention further relates to liquid compositions containing solid fine particles, such as organic or inorganic pigments and fillers, and the novel polymers P and their salts as dispersants. The polymers P have at least one functional group of the formula (I) bound to one of the termini and/or to the backbone of the polymer: formula (I) where # indicates the point of attachment to the terminus and/or to the polymer backbone and the variables k, m, A, Q, R1, R2, X and Y are as defined in claim 1.
