Claims
- 1. A curable composition comprising an initiator; an anionically-polymerized addition polymer of at least one ester of methacrylic acid wherein the polymer comprises mers having the formula ##STR8## wherein R is an acryloyloxyalkyl or a methacryloyloxyalkyl group, having up to 4 carbon atoms in the alkyl portion,
- and wherein n, the average chain length of the polymer, is about 6 to 50 mers; and, optionally, a pigment.
- 2. The polymer of claim 1 wherein the anionically-polymerized polymer is an alkoxide-polymerized polymer.
- 3. The polymer of claim 2 wherein at least about 85% by weight of the molecules of the polymer have chain lengths of about .sqroot.2n to about 2n mers.
- 4. The polymer of claim 3 wherein the average chain length is about 6 to about 25 mers.
- 5. The polymer of claim 3 wherein the polymer also comprises mers having the formula ##STR9## wherein R.sup.1 is a (C.sub.1 -C.sub.24)alkyl group.
- 6. The polymer of claim 5 wherein R.sup.1 is a (C.sub.1 -C.sub.4)alkyl group.
- 7. A composition comprising an anionically-polymerized addition polymer of at least one ester of methacrylic acid wherein the polymer comprises mers having the formula ##STR10## wherein R is an acryloyloxyalkyl or a methacryloyloxyalkyl group, having up to 4 carbon atoms in the alkyl portion,
- and wherein n, the average chain length of the polymer, is about 6 to 50 mers; about 1 to 50% by weight of water or an organic solvent; and, optionally, a pigment.
- 8. The composition of claim 7 wherein the anionically-polymerized polymer is an alkoxide-polymerized polymer wherein at least about 85% by weight of the molecules of the polymer have chain lengths of about .sqroot.2n to about 2n mers.
- 9. The polymer of claim 7 wherein the average chain length is about 6 to about 25 mers.
- 10. The polymer of claim 7 wherein the polymer also comprises mers having the formula ##STR11## wherein R.sup.1 is a (C.sub.1 -C.sub.24) alkyl group.
- 11. The polymer of claim 10 wherein R.sup.1 is a (C.sub.1 -C.sub.4) alkyl group.
- 12. A process comprising mixing an anionically-polymerized addition polymer of at least one ester of methacrylic acid wherein the polymer comprises mers having the formula ##STR12## wherein R is an acryloyloxyalkyl or a methacryloyloxyalkyl group, having up to 4 carbon atoms in the alkyl portion,
- and wherein n, the average chain length of the polymer, is about 6 to 50 mers, with an initiator and curing the mixture.
