Claims
- 1. A composition comprising a salt of an unsaturated carboxylic acid and an amine-functionalized styrene-maleic anhydride imide copolymer.
- 2. The composition of claim 1 wherein the unsaturated carboxylic acid is selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, fumaric acid, and an unsaturated hemi-ester of a dicarboxylic anhydride, and cinnamic acid.
- 3. The composition of claim 1 wherein the amine-functionalized styrene-maleic anydride imide copolymer is an imide copolymer prepared from styrene-maleic anhydride copolymer (SMA) and a polyamine compound having a primary amine and at least one tertiary amine.
- 4. The composition of claim 1 wherein the amine-functionalized styrene-maleic anydride imide copolymer is an imide copolymer prepared from styrene-maleic anhydride copolymer (SMA) and a an N,N-dialkylaminoalkyl amine.
- 5. The composition of claim 1 wherein the amine-functionalized styrene-maleic anydride imide copolymer is an imide copolymer prepared from styrene-maleic anhydride copolymer (SMA) and N,N-dimethylaminopropyl amine.
- 6. A composition comprising a solution of the salt of claim 1 in water, an organic solvent, UV/EB-curable organic monomer, and/or UV/EB curable organic oligomer.
- 7. The composition of claim 1 further including a photoinitiator and being curable under UV or EB conditions.
- 8. The composition of claim 1 in the form of a pigment dispersion, ink, varnish, wood coating, or metal coating.
- 9. The composition of claim 1 in the form of a pigment dispersion which comprises pigment, water, defoamer, and non-ionic surfactant.
- 10. A method comprising dispersing, emulsifying, crosslinking, hardening, or conferring adhesion properties to a polymer, oligomer, or monomer by adding a salt of an unsaturated carboxylic acid and an amine-functionalized styrene-maleic anhydride imide copolymer to the polymer, oligomer, or monomer.
- 11. A composition prepared by curing the composition of claim 1.
- 12. The composition of claim 11 in the form of a coating or paint.
- 13. A method of curing the composition of claim 1 comprising Michael addition, free radical polymerization, or radiation curing.
- 14. A copolymer of the salts of claim 1 prepared by reacting the salt with a different ethylenically unsaturated monomer or oligomer.
- 15. A homopolymer of the salt of claim 1.
- 16. A method of preparing a composition according to claim 1 comprising reacting an amine-functionalized styrene-maleic anhydride imide with an unsaturated carboxylic acid to form a salt.
- 17. A salt prepared according to the method of claim 16.
