PURPOSE: A copolymer using as a dispersant for metal powder is provided to maintain dispersity which is stable and continuous in the dispersed liquid of metal powder. CONSTITUTION: A copolymer comprises a repeating unit 1 in chemical formula 1, and a repeating unit 2 in chemical formula 2. In chemical formula 1 and 2, R1 is hydrogen or a methyl group, R2 is a single bond, C1-4 alkylene or -C(O)O-, R3 is C10-35 aryl group having 2-5 aromatic rings, R3 is hydrogen or a methyl group, R5 is hydrogen or -COOH, R6 is hydrogen or a methyl group, R7 is a single bond, C1-4 alkylene, C6-12 arylene, -C(O)O-, -C(O)NH- or -C(O)-R9-R10-, and R8 is an ionic functional group. |
