Patent ID: 8168366

Claim:
A polymer comprising (i) a first olefinic monomer having the formula: wherein X 1 is selected from C 2-3 alkylenyl or fluorinated alkylenyl or C 4-20 cycloalkylenyl; R 2 is selected from C 2-6 alkyl or C 4-20 cycloalkyl each optionally containing one or more heteroatoms; and where R 3 and R 4 are independently each selected from hydrido, C 1-6 alkyl, C 4-20 cycloalkyl or C 1-6 alkoxy and n is 3-8; and (ii) a second olefinic monomer selected from the group consisting of: (a) a hydroxy containing olefinic monomer having the formula: wherein X 2 is selected from C 3-4 alkylenylcarbonyloxy, C 5-20 cycloalkylenylcarbonyloxy or C 4-20 cycloalkylenyl each optionally substituted with one or more fluoro substituents; R 8 is C 1-6 alkyl or C 4-20 cycloalkyl each optionally substituted with one or more substituents selected from hydroxy and fluoro substituents; p is 0 or 1; R 6 is selected from hydrido, trifluoromethyl, difluoromethyl, fluoromethyl, or C 1-6 alkyl or C 4-8 cycloalkyl each optionally substituted with one or more fluoro substituents, and R 7 is selected from trifluoromethyl, difluoromethyl, fluoromethyl or C 1-6 alkyl or C 4-8 cycloalkyl substituted with one or more fluoro substituents and further R 6 and R 7 can be linked to form a cyclic group, (b) a hydroxy containing olefinic monomer having the formula: wherein X 1 is selected from C 2-3 alkylenyl or fluorinated alkylenyl or C 4-10 cycloalkylenyl; R 5 is C 1-20 alkyl or C 4-8 cycloalkyl each optionally substituted with one or more substituents selected from hydroxy and fluoro substituents; R 6 is selected from hydrido, trifluoromethyl, difluoromethyl, fluoromethyl, or C 1-6 alkyl or C 4-8 cycloalkyl each optionally substituted with one or more fluoro substituents, and R 7 is selected from trifluoromethyl, difluoromethyl, fluoromethyl or C 1-6 alkyl or C 4-8 cycloalkyl substituted with one or more fluoro substituents and further R 6 and R 7 can be linked to form a cyclic group, and (c) a sulfonylamido containing olefinic monomer having the formula: wherein X 2 is selected from C 3-4 alkylenylcarbonyloxy or C 5-20 cycloalkylenylcarbonyloxy or C 4-20 cycloalkylenyl each optionally substituted with one or more fluoro substituents; R 10 is C 1-6 alkyl or C 4-20 cycloalkyl each optionally substituted with one or more fluoro substituents; m is 0 or 1; and R 9 is C 1-4 alkyl or C 4-20 cycloalkyl each optionally substituted with one or more fluoro substituents.
