Title (EN) PHENOLATE CONSTRAINED GEOMETRY METALLOCENE OLEFIN POLYMERIZATION CATALYST, METHOD OF MAKING, AND METHOD OF USING
(FR) CATALYSEUR A GEOMETRIE CONTRAINTE DE METALLOCENE ET PHENOLATE POUR LA POLYMERISATION D'OLEFINES, SON PROCEDE D'OBTENTION, ET SON PROCEDE D'UTILISATION
Abstract: front page image
(EN)Preparation of the compound (Ar'R¿4?)O(Ar'R'¿4?)M(CH¿2?Ph)¿2? is performed by adding (Ar'R¿4?)(Ar'R'¿4?)OH to M(CH2Ph)¿4?, where Ar' is phenyl or naphthyl, Ar' is cyclopentadienyl or indenyl, R and R' are independently H or C1-10 alkyl groups, M is a group 4 transition metal. The compound is activated toward polymerization of alpha olefins by any of the cocatalysts methylalumoxane, B(ArF)¿3?, and Ph¿3?C?+¿B(ArF)¿4??-¿.
(FR)Le composé R'(Ar'R¿4?)O(Ar'R'¿4?)M(CH¿2?Ph)¿2? s'obtient par adjonction de (Ar'R¿4?)(Ar'R'¿4?)OH à M(CH2Ph)¿4?, formules dans lesquelles Ar' est phényle ou naphtyle, Ar' est cyclopentadiényle ou indényle, R et R' sont indépendamment des groupes H ou C1-10 alkyle, et M est un métal de transition du groupe 4. Le composé est activé en vue de la polymérisation d'alpha oléfines par l'un des cocatalyseurs méthylalumoxane, B(ArF)¿3?, et Ph¿3?C?+¿B(ArF)¿4??-¿.
