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.
Claims21
A polymer comprising N-functional imide groups prepared from reactants comprising:
- (a) an ethylenically unsaturated anhydride or diacid monomer;
- (b) at least one co-monomer that is different from (a) comprising an ethylenically unsaturated group that is reactive with (a);
- and
- (c) at least one compound reactive with the anhydride or diacid functional groups of (a) that is represented by Chemical Formula I:
- H2N—R1 (I),
- wherein R1 is NH2,
- wherein a molar ratio of the ethylenically unsaturated anhydride or diacid monomer (a) to the at least one co-monomer (b) is within a range from 1:1 to 1:100, and
- wherein the at least one co-monomer comprises an ethylenically unsaturated non-aromatic compound.
A pigment dispersion comprising:
- (1) a polymer comprising N-functional imide groups prepared from reactants comprising:
- (a) an ethylenically unsaturated anhydride or diacid monomer;
- (b) at least one co-monomer that is different from (a) comprising an ethylenically unsaturated group that is reactive with (a);
- and
- (c) at least one compound reactive with the anhydride or diacid functional groups of (a) that is represented by Chemical Formula I:
- H2N—R1 (I),

- wherein a molar ratio of the ethylenically unsaturated anhydride or diacid monomer (a) to the at least one co-monomer (b) is within a range from 1:1 to 1:100, and
- wherein the at least one co-monomer comprises an ethylenically unsaturated non-aromatic compound;
- and
- (2) pigment.
