Title
(EN) PROCESS TO PREPARE A SOLID SUPPORT FOR A PROCATALYST FOR POLYMERIZATION OF OLEFINS
(FR) PROCÉDÉ DE PRÉPARATION D'UN SUPPORT SOLIDE POUR UN PROCATALYSEUR DE POLYMÉRISATION D'OLÉFINES
Abstract
(EN) A process for the preparation of a solid support for a procatalyst suitable for preparing a catalyst composition for olefin polymerization, said process comprising: A. providing or preparing a compound R4zMgX42-z wherein: R4 is independently selected from linear, branched or cyclic hydrocarbyl group independently selected from alkyl, alkenyl, aryl, aralkyl, or alkylaryl groups, and one or more combinations thereof; X4 is independently selected from the group consisting of fluoride, chloride, bromide or iodide; and 0 < z < 2; and B. contacting the compound R4zMgX42-z with a silane compound Si(OR5)4-n(R6)n to give a Mg(OR1)xX12-x wherein: R1, R5 and R6 are each independently selected from linear, branched or cyclic hydrocarbyl group independently selected from alkyl, alkenyl, aryl, aralkyl, alkoxycarbonyl or alkylaryl groups, and one or more combinations thereof; Х1 is independently selected from the group consisting of fluoride, chloride, bromide or iodide; n is in range of 0 to 4; 0 < z < 2; and 0 < x < 2; wherein an initiator compound, selected from the group consisting of a ketone, a diketone, an ester, a diester and a benzamide, is added during step B to obtain a solid support.
(FR) L'invention concerne un procédé de préparation d'un support solide pour un procatalyseur approprié pour la préparation d'une composition de catalyseur pour la polymérisation d'oléfines, ledit procédé comprenant : A. la fourniture ou la préparation d'un composé R4 zMgX4 2-z dans lequel : R4 est indépendamment sélectionné parmi un groupe hydrocarbyle linéaire, ramifié ou cyclique indépendamment sélectionné parmi des groupes alkyle, alcényle, aryle, aralkyle, ou alkylaryle, et une ou plusieurs combinaisons de ceux-ci ; X4 est indépendamment sélectionné dans le groupe constitué par le fluorure, le chlorure, le bromure ou l'iodure ; et 0 < z < 2 ; et B) mise en contact du composé R4 zMgX4 2-z avec un composé silane Si(OR5)4-n(R6)n pour donner Mg(OR1)xX1 2-x dans lequel : R1, R5 et R6 sont chacun indépendamment sélectionnés parmi un groupe hydrocarbyle linéaire, ramifié ou cyclique indépendamment sélectionné parmi des groupes alkyle, alcényle, aryle, aralkyle, alcoxycarbonyle ou alkylaryle, et une ou plusieurs combinaisons de ceux-ci ; Х1 est indépendamment sélectionné dans le groupe constitué par le fluorure, le chlorure, le bromure ou l'iodure ; n est dans la plage de 0 à 4 ; 0 < z < 2 ; et 0 < x < 2 ; un composé initiateur, sélectionné dans le groupe constitué d'une cétone, d'une dicétone, d'un ester, d'un diester et d'un Benzamide, étant ajouté lors de l'étape B pour obtenir un support solide.
