  • Polymers with functional imide groups and pigment dispersions and coatings formed therefrom
    Patent number: 10273317
    Abstract: A polymer having N-functional imide groups is prepared from reactants that include: (a) an ethylenically unsaturated anhydride or diacid monomer; (b) at least one co-monomer that is different from (a) having an ethylenically unsaturated group that is reactive with (a); and at least one compound reactive with the anhydride or diacid functional groups of (a) that is represented by Chemical Formula I: H2N—R1. With respect to Chemical Formula I, R1 is selected from NH2 or OH. Pigment dispersions and coating compositions are also prepared with the polymers having N-functional imide groups.
    Type: Grant
