HEAVY-HYDROGENATED (METH)ACRYLATES, PROCESS FOR PRODUCING THEM, POLYMERS THEREOF AND OPTICAL MEMBERS

摘要

A novel compound represented by a formula [ 1] wherein R<1 >and R<2 >respectively represent a heavy or light hydrogen atom, R<3 >represents a heavy or light hydrogen atom or a methyl group in which three hydrogen atoms are respectively heavy or light hydrogen atoms, R<4 >represents a condensed ring group composed of a norbornane ring and a C5-7 hydrocarbon ring provided that at least one hydrogen atom contained in the condensed ring group is a heavy hydrogen atom; and a novel polymer produced by polymerization of a composition comprising the compound are disclosed.
