Abstract

Olefins are polymerised in contact with a catalyst system contg. (a) a solid catalytic complex based on Mg, a transition metal and a halogen, obtd. by (i) reacting (I) an oxygenated organo-Mg cpd. or a halogenated Mg cpd. with (II) an oxygenated organic cpd. or a halogenated cpd. of a transition metal of Gps. IVB or VB, to give a liq. complex, (ii) precipitating. the complex by means of a cpd. of formula AlRnX3-n, to give a solid catalytic complex, (iii) sepg. the solid complex, and (iv) treating the solid complex with a cpd. of formula AlRnX3-n, and (b) an organic cpd. of a metal of Gps. IA, IIA, IIB, IIIA or IVB. R = hydrocarbo gp.; X = halogen; n = less than 3.
