Title (EN) MAGNESIUM-ZIRCONIUM ALKOXIDE COMPLEXES AND POLYMERIZATION CATALYSTS MADE THEREFROM
(FR) COMPLEXES A BASE D'ALCOXYDE DE MAGNESIUM-ZIRCONIUM ET CATALYSEURS DE POLYMERISATION ELABORES AVEC CES COMPLEXES
Abstract:
(EN) A mixed metal-containing precursor is disclosed whereby the precursor includes: a) MgZrMx where M is selected from one or more metals having a +3 or +4 oxidation state, x is from 0 to about 2, and where the molar ratio of magnesium to the mixture of zirconium and M is within the range of from about 2.5 to 3.6; and b) at least one moiety complexed with component a) selected from the group consisting of alkoxide groups, phenoxide groups, halides, hydroxy groups, carboxylate groups, amide groups, and mixtures thereof. A polymerization procatalyst prepared from the mixed metal containing precursor, methods of making the precursor and procatalyst, as well as polymerization methods using the procatalyst also are disclosed.
(FR) L'invention concerne un précurseur métallique mixte comprenant : a) MgZrMx, M pouvant être un ou plusieurs métaux à état d'oxydation +3 ou +4, x valant de 0 à 2 environ, pour un rapport molaire entre le magnésium et le mélange zirconium et M allant d'environ 2,5 à 3,6; et b) au moins une fraction, en complexation avec le composant a), pouvant appartenir aux catégories suivantes : groupes alcoxyde, groupes phénoxyde, halogénures, groupes hydroxy, groupes carboxylate, groupes amide, et leurs mélanges. L'invention concerne en outre un procatalyseur de polymérisation élaboré à partir de ce précurseur, des procédés relatifs à l'élaboration du précurseur et du procatalyseur, et des procédés de polymérisation faisant appel audit procatalyseur.
