| 摘要 |
The invention relates to a copolymer that can be obtained by the polymerization of the monomers (A), (B) and (C), (A) being a monomer of formula (I) wherein A is C2-C4 alkylene and B is a C2-C4-alkylene different from A, k corresponds to the number 0 or 1, m is a number between 0 and 500, n is a number between 0 and 500, the sum of m+n being equal to between 1 and 1000; (B) contains an ethylenically unsaturated monomer containing an aromatic group; and (C) is an ethylenically unsaturated monomer containing an alkyl radical. The copolymers according to the invention are suitable as dispersants for pigments.
