Claims
- 1. An acid-functional polymer which comprises the free radical polymerization reaction product of:
- (i) 1% to 100% by weight of an unsaturated acid-functional monomer having the structure: ##STR6## wherein R.sup.1 is hydrogen or methyl and Z is nothing or is a divalent alkyl radical having 1 to about 20 carbon atoms; and
- (ii) 0% to 99% by weight of at least one other unsaturated monomer copolymerizable with the unsaturated acid-functional monomer.
- 2. The polymer of claim 1 wherein R.sup.1 is hydrogen.
- 3. The polymer of claim 2 wherein Z is nothing.
- 4. The polymer of claim 1 wherein R.sup.1 is methyl.
- 5. The polymer of claim 4 wherein Z is nothing.
- 6. The polymer of claim 1 wherein Z is a divalent polymethylene chain--(--CH.sub.2 --).sub.n --wherein n is 1 to 20.
- 7. The polymer of claim 1 wherein the polymer is the reaction product of 5 to about 30 weight percent of the unsaturated acid-functional monomer and 70 to 95 weight percent of at least one other unsaturated monomer copolymerizable with the unsaturated acid-functional monomer.
- 8. The polymer of claim 7 wherein at least one of the unsaturated monomers copolymerizable with the acid-functional monomer is a hydroxyl-functional monomer.
