Patent ID: 7014980

Claim:
A composition comprising a polymer, said polymer comprising at least one acrylate or methacrylate monomer having a formula where R 1 represent hydrogen (H), a linear or branched alkyl group of 1 to 20 carbons, or a semi- or perfluorinated linear or branched alkyl group of 1 to 20 carbons; and where R 2 represents an unsubstituted aliphatic group or a substituted aliphatic group having zero or one trifluoromethyl (CF 3 ) group attached to each carbon of the substituted aliphatic group, or a substituted or unsubstituted aromatic group; and where R 3 represents hydrogen (H), methyl (CH 3 ), trifluoromethyl (CF 3 ), difluoromethyl (CHF 2 ), fluoromethyl (CH 2 F), or a semi- or perfluorinated aliphatic group; and where R 4 represents trifluoromethyl (CF 3 ), difluoromethyl (CHF 2 ), fluoromethyl (CH 2 F), or a semi- or perfluorinated substituted or unsubstituted aliphatic group; and wherein at least one of the monomers is selected from the group consisting of 1,1,1-trifluoro-2-trifluoromethyl-2-hydroxy-5-pentyl methacrylate, or its analogous acrylate; 1,1,1 -trifluoro-2-trifluoromethyl-2-hydroxy-4-pentyl methacrylate, or its analogous acrylate; or 2-{[5-(1′,1′,1′-trifluoro-2′-trifluoromethyl-2′-hydroxy)propyl]norbornyl]}methacrylate, or its analogous acrylate.
