Title (EN) PRE-POLYMERIZED CATALYST COMPONENTS FOR THE POLYMERIZATION OF OLEFINS
(FR) CONSTITUANTS CATALYTIQUES PRE-POLYMERISES SERVANT A LA POLYMERISATION D'OLEFINES
Abstract: front page image
(EN)Catalyst components for the preparation of ethylene (co)polymers capable to produce polymers with high bulk density, to avoid the problems of formation of fines and that have a high activity are provided. Said catalyst components are characterized by comprising a non-stereospecific solid catalyst component, comprising a titanium compound and a magnesium dihalide, which is pre-polymerized with an alpha olefin CH¿2?=CHR?I¿ wherein R is a C1-C8 alkyl group, to such an extent that the amount of the $g(a)-olefin pre-polymer is up to 100 g per g of said solid catalyst component.
(FR)L'invention concerne des constituants catalytiques servant à la préparation de (co)polymères d'éthylène capables de produire des polymères avec une masse volumique apparente élevée afin d'éviter les problèmes de formation de fines, ces constituants présentant un activité élevée. Ces constituants catalytiques sont caractérisés en ce qu'il comprennent un constituant catalytique solide non stéréospécifique, un composé de titane et un dihalogénure de magnésium pré-polymérisé avec une alpha-oléfine CH¿2?=CHR?I¿ où R représente un groupe alkyle C1-C8, la quantité du pré-polymère d'$g(a) oléfine pouvant aller jusqu'à 100 g par g de ce constituant catalyseur solide.
