Patent

CA 2533415

A novel compound represented by a formula [ 1] wherein R1 and R2respectively represent a heavy or light hydrogen atom, R3 represents a heavy or light hydrogen atom or a methyl group in which three hydrogen atoms are respectively heavy or light hydrogen atoms, R4 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.

L'invention concerne un composé représenté par la formule (1) dans laquelle R?1 ¿et R?2 ¿représentent respectivement un atome d'hydrogène lourd ou léger, R?3 ¿représente un atome d'hydrogène lourd ou léger ou un groupe méthyle dans lequel trois atomes d'hydrogène sont respectivement des atomes d'hydrogène lourds ou légers, et R?4 ¿représente un groupe cyclique condensé composé d'un cycle de norbornane et d'un cyle d'hydrocarbure C¿5-7 ?à condition qu'au moins un atome d'hydrogène contenu dans le groupe cyclique condensé soit un atome d'hydrogène lourd. L'invention concerne également un nouveau polymère produit par polymérisation d'une composition comprenant ledit composé.
