Abstract

Prodn. of polyolefins (I) by polymerisation of alpha-olefins at 50-150 deg.C and 1-40 bar in the presence of a catalyst consisting of a transition metal component (A) and an organometallic cpd. (component B); the novelty is that (A) is prepd. without sepn. of intermediates, by (a) reaction of an organomagnesium cpd. of formula (n-Bu)x(n-octyl)yMg (II) (with x = 1.2-1.7; y = 0.3-0.8) with 0.5-2.5 mols. chlorinated hydrocarbon (III) (w.r.t. 1 mol. II) at 30-110 deg.C, (b) treatment of the suspension obtd. with 0.1-1 mol. electron donor (IV) (per g-atom Mg in the solid) at 0-100 deg.C and (c) reaction of the support material obtd. with 0.5-2 mols. (per g-atom Mg in the support) of a cpd. of formula TiXm(OR)4-m (V), at 30-120 deg.C (with R = 2-10C alkyl; X = Hal; m = 0-4). Pref. (IV) is diethyl sulphite (IVA) or Me2Si(OEt)2 (IVE), and (V) is TiCl4.
