Title (EN) COBALT OR NICKEL PRE-CATALYST AND USE THEREOF IN OLEFIN POLYMERISATION
(FR) PRÉ-CATALYSEUR À BASE DE COBALT OU DE NICKEL ET SON UTILISATION DANS LA POLYMÉRISATION D'OLÉFINES
Abstract:
(EN) The invention relates to a pre-catalyst for olefin polymerisation, of formula MuMalc vXw(LA)y(LB)z, wherein M is the cobalt or the nickel; Malc is an alkali metal and/or an alkaline-earth metal; X is an anion; LA is a Lewis acid; LB is a Lewis base; u is comprised between 0.001 and 10; v is an integer > 1; w is comprised between 1 and 20; y is comprised between 0 and 10; and z is comprised between 0 and 10. The invention also relates to a method for preparing said pre-catalyst, as well as the use thereof in a method for polymerising ethylene or propene or for copolymerising ethylene or propene with at least one (polar and/or apolar) α-olefin.
(FR) L'invention concerne une pré-catalyseur pour la polymérisation d'oléfïnes, de formule MuMalcvXw(LA)y(LB)z; M étant le cobalt ou le nickel; Malc étant un métal alcalin et/ou un métal alcalino-terreux; - X étant un anion; LA étant un acide de Lewis; LB étant une base de Lewis; u étant compris entre 0,001 et 10; v étant un nombre entier > 1; - w étant compris entre 1 et 20; y étant compris entre 0 et 10; z étant compris entre 0 et 10. Elle concerne également un procédé de préparation de ce pré-catalyseur, ainsi que son utilisation dans un procédé de polymérisation de l'éthylène ou du propène ou de copolymérisation de l'éthylène ou du propène avec au moins une α-oléfïne (polaire et/ou apolaire).
