Abstract

L'invention a pour objet un perfectionnement à la polymérisation d'alpha-oléfines. Dans le procédé de polymérisation qui comporte l'utilisation d'un catalyseur obtenu par réaction d'un halogénure de métal trivalent avec un composé de métal divalent pour obtenir un produit solide I, qu'on fait réagir avec un ou plusieurs donneurs d'électrons et un ou plusieurs accepteurs d'électrons pour former un produit solide II que l'on combine finalement avec un composé d'organo-aluminium, l'invention prévoit de faire réagir au moins un donneur et/ou un accepteur d'électrons en au moins deux portions divisées, l'un des accepteurs étant obligatoirement TiCl4 . Obtention d'un polymère hautement cristallin avec un rendement élevé et sans obligation de débarrasser le polymère du restant de catalyseur.The subject of the invention is an improvement in the polymerization of alpha-olefins. In the polymerization process which comprises the use of a catalyst obtained by reacting a trivalent metal halide with a divalent metal compound to obtain a solid product I, which is reacted with one or more electron donors and one or more electron acceptors to form a solid product II which is finally combined with an organoaluminum compound, the invention provides for reacting at least one electron donor and / or one electron acceptor in the minus two divided portions, one of the acceptors necessarily being TiCl4. Obtaining a highly crystalline polymer with a high yield and without having to remove the catalyst residue from the polymer.
