Abstract
The invention relates to a novel octafluorotricyclodecane derivative represented by the general formula (1), where R1 is a hydrogen atom, a halogen atom, a hydrocarbon group or a halogenated hydrocarbon group, m is 0 or 1, and R2 is represented by the general formula (2), where R3 is a hydrogen atom or a hydrocarbon group optionally having a substituent. This octafluorotricyclodecane derivative may be useful as a monomer for producing various functional polymers or as a raw material of the same.
