Title (EN) CATALYST FOR PRODUCING LIVING OLEFIN POLYMER AND PROCESS FOR PRODUCING THE POLYMER
(FR) PROCEDE POUR LA PRODUCTION DE POLYMERE D'OLEFINE VIVANT ET PROCEDE DE PRODUCTION DE CE POLYMERE
Abstract: front page image
(EN)A catalyst comprising an organoaluminum compound and a vanadium chelate compound having the ability to cause olefins to undergo living coordination polymerization is contacted with a terminal diolefin to obtain a catalyst for living polymer production. When the above contact is conducted in the presence of a cycloolefin or an internal olefin, the yield of a living polymer can be improved. By modifying all ends of the living polymer obtained, a telechelic olefin polymer is obtained in which all the polymer chains have been modified with functional groups.
(FR)Un catalyseur comprenant un composé d'organoaluminium et un composé chélate de vanadium capable d'amener des oléfines à subir une polymérisation de coordination vivante est mis en contact avec une dioléfine terminale, pour produire un catalyseur permettant la production de polymère vivant. Lorsque ce contact est effectué en présence d'une cyclo-oléfine ou d'une oléfine interne, la production de polymère vivant peut être améliorée. En modifiant toutes les extrémités du polymère vivant ainsi obtenu, on obtient un polymère d'oléfine téléchélique dans lequel toutes les chaînes polymères sont modifiées avec des groupes fonctionnels.
