PROBLEM TO BE SOLVED: To provide a novel dispersant which overcomes the conventional drawbacks, can be easily produced, and is characterized by particularly good technical properties in use. SOLUTION: A maleic anhydride copolymer containing amine oxide groups is obtained by reacting at least 1 mol% of the anhydride groups of the maleic anhydride copolymer with a diamine and subsequently oxidizing to form amine oxide groups. |
