Abstract

C2-10 olefins are homo- or copolymerized by use of a catalyst prepared by treating with an aluminium tri-C1-8-alkyl a mixture obtained from a reducible compound of a Group IV-VIa transition metal and an alumino-organic compound which may also contain halogen, the aluminium trialkyl being used in a quantity equivalent to the amount of aluminium monoalkyl dihalide that has formed in the preparation of said mixture, or in a deficiency up to 20 mol. per cent or in an excess up to 30 mol. per cent thereof. The said mixture is preferably heated at 40 DEG -150 DEG C. before treatment with aluminium trialkyl. Olefins mentioned are of the type CH2=CHR wherein R is H or Me, Et, Pr, Bu or pentyl. In the examples ethylene and propylene are polymerized, specified catalyst ingredients being TiCl4 (converted to TiCl3), Et3Al2Cl3 (which may contain excess EtAlCl2) and AlEt3.
