The present invention relates to novel polymer compositions, to a process for their manufacturing, to the use of said polymer compositions as dispersants and to liquid compositions containing solid fine particles, such as organic or inorganic pigments and fillers, and the novel polymer compositions as dispersants. The polymer compositions are obtainable by reacting: a) a polymer P1 having at least one functional group of the formula (I), and a polymer backbone B where # indicates the point of attachment to the terminus and/or to the polymer backbone B of the polymer P1; k is 0, 1, 2, 3 or 4, in particular 0 or 1, especially 0; m is 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9, in particular 0 or 1, especially 0; A is a chemical bond or a divalent moiety selected from the group consisting of C1-C6 alkylene, -O-(C2-C6 alkylene), -C(=O)-O-(C2-C6 alkylene), -NR3-(C2-C6 alkylene) and C(=0)-NR3-(C2-C6 alkylene), where the C2-C6 alkylene part is attached to Q; Q is a divalent moiety selected from the group consisting of -0-, -NH- and -S-R1, R2, R3 are as defined in the claims; with a polymer P2 which is a polyolefine succinic anhydride, in particular a polyisobutene succinic anhydride. |
