Carboxyl-group-containing copolymer, and method for producing same |
| abstract |
The present invention provides a carboxyl group-containing copolymer having a better calcium ion trapping ability and a better carbon black dispersing ability than any conventional carboxyl group-containing copolymers. The present invention relates to a carboxyl group-containing copolymer including a structural unit (a) derived from an unsaturated monocarboxylic acid monomer (A), a structural unit (b) derived from an unsaturated dicarboxylic acid monomer (B), and a structural unit (c) derived from a cationic monomer (C). |
