  • Publication number: 20190092903
    Abstract: The present invention relates to polyalkylene imine based polymers, which have aliphatic polyester groups attached to the polyalkylenimine backbone via an carboxamide group. The novel polymers are particularly useful as dispersants for pigments, in particular as dispersants for pigments in non-aqueous compositions. The polyalkylene imine based polymers are characterized by having a) a polyalkylene imine backbone; b) at least one aromatic moiety P.1, which is bound to a nitrogen atom of the polyalkylene imine backbone via an carboxamide or carboximide group; and c) at least one aliphatic polyester moiety P.2, which is bound to a nitrogen atom of the polyalkylene imine backbone via an carboxamide group.
