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: HN—R. With respect to Chemical Formula I, Ris selected from NHor OH. Pigment dispersions and coating compositions are also prepared with the polymers having N-functional imide groups.
