Claims15
A copolymer produced by the process consisting of polymerizing (1) one or more olefinically unsaturated monomers selected from the group consisting of maleic acid, maleic anhydride, t-butylacrylamide, 2-acrylamido-2-methyl propane sulfonic acid (AMPS), vinyl acetate, vinyl cyclopropane, vinyl cyclopentane, vinyl cyclohexane, and any combination thereof and (2) at least one monomer comprising the formula IV
- wherein R1-R4 and R7, independently, is selected from the group consisting of hydrogen, an alkyl group, a cycloalkyl group, a heteroalkyl group, a heterocycloalkyl group, an aryl group, a heteroaryl group, a protecting group, or a combination thereof, or R2 and R4 form a substituted or unsubstituted cycloalkyl group, wherein R1-R4 and R7 are not simultaneously hydrogen.
A method for making a copolymer consisting of polymerizing (1) one or more olefinically unsaturated monomers selected from the group consisting of maleic acid, maleic anhydride, t-butylacrylamide, 2-acrylamido-2-methyl propane sulfonic acid (AMPS), vinyl acetate, vinyl cyclopropane, vinyl cyclopentane, vinyl cyclohexane, and any combination thereof and (2) at least one monomer comprising the formula IV
- wherein R1-R4 and R7 comprises, independently, hydrogen, an alkyl group, a cycloalkyl group, a heteroalkyl group, a heterocycloalkyl group, an aryl group, a heteroaryl group, a protecting group, or a combination thereof, wherein the polymerization product is not polyisopropenylphosphonic acid.
