ABSTRACT:
The present invention relates to a polymerizable monomer represented by the general formula (1),wherein R1is a hydrogen atom, a halogen atom, a hydrocarbon group or a fluorine-containing alkyl group; R2is a straight-chain or branched alkyl group, a cyclic alkyl group, an aromatic group, or a substituent having at least two of these groups, the R2being optionally partially fluorinated; R3is a hydrogen atom, a hydrocarbon group that is optionally branched, a fluorine-containing alkyl group, or a cyclic group having an aromatic or alicyclic structure, the R3optionally containing a bond of an oxygen atom or carbonyl group; and n is an integer of 1–2.
