Patent ID: 8530692

Claim:
A compound having a general formula (1), wherein n is an integer from 2 to 5, R 0 represents an (n+1)-valent linear or branched aliphatic hydrocarbon group having 1 to 10 carbon atoms, or an (n+1)-valent alicyclic hydrocarbon group having 3 to 20 carbon atoms, R 1 represents a hydrogen atom, a methyl group, or a trifluoromethyl group, R 2 represents a single bond, a methylene group, an ethylene group, a 1-methylethylene group, a 2-methylethylene group, or a divalent alicyclic hydrocarbon group having 4 to 20 carbon atoms, each R 2 is a same as or different from each other, each R 3 independently represents a monovalent alicyclic hydrocarbon group having 4 to 20 carbon atoms or a linear or branched alkyl group having 1 to 4 carbon atoms, or each R 3 independently represents a monovalent alicyclic hydrocarbon group having 4 to 20 carbon atoms or a linear or branched alkyl group having 1 to 4 carbon atoms, and two of R 3 groups bond to form a divalent alicyclic hydrocarbon group having 4 to 20 carbon atoms together with the carbon atom bonded to the two of R 3 groups, X represents a linear or branched fluoroalkylene group having 1 to 10 carbon atoms, and each X is a same as or different from each other.
