Abstract
Procedure for the polymerization of olefins or for the copolymerization of olefins under pressures of less than 20 bar, of the formula CH2 = CHR, in which R is a hydrogen atom or an alkyl radical with a maximum of 8 carbon atoms, characterized in that it comprises In a first stage, preactivate a solid compound of a transition metal of subgroups IVa, Va and VIa of the periodic classification of the elements in which the transition metal is, at least in part, in a state of valence lower than maximum, this pre-activation being effected by bringing the transition metal compound into contact with an organomagnesian compound, and then, in a second step, the olefins are polymerized in the presence of the pre-activated transition metal compound and a compound organoaluminum.
