Title (EN) POLYMERIZABLE ADAMANTANE DERIVATIVES AND PROCESS FOR PRODUCING THE SAME
(FR) DERIVES POLYMERISABLES DE L'ADAMANTANE ET LEUR PROCEDE DE PRODUCTION
Abstract:
(EN) High yields of polymerizable adamantane derivatives each having at least one polymerizable unsaturated group are produced by the esterification or amidation of a compound of general formula (1a) and a polymerizable unsaturated compound (e.g. an alcohol, a carboxylic acid or an amine) in the presence of a catalyst comprising a compound of a Group 3 element of the periodic table, such as a samarium compound. In said formula, R1a to R4a represent each a substituent selected from among inert atoms, inert groups, hydroxyl, carboxyl and amino, provided at least two groups of R1a to R4a are hydroxyl, carboxyl or amino.
(FR) On obtient avec des rendements élevés des dérivés polymérisables de l'adamantane, renfermant au moins un groupe insaturé polymérisable, par estérification ou amidation d'un composé de formule générale (1a) (dans laquelle R1a, R2a, R3a et R4a représentent un substituant choisi entre les atomes inertes, les groupes inertes, hydroxyle, carboxyle et amino, à condition qu'au moins deux groupes de R1a, R2a, R3a ou R4a soient hydroxyle, carboxyle ou amino) et d'un composé insaturé polymérisable (alcool, acide carboxylique ou amine), en présence d'un catalyseur renfermant un composé contenant un élément du groupe 3 de la classification périodique, tel qu'un composé contenant du samarium.
