Abstract
Process of polymerization of olefins at low pressure, characterized in that it is carried out in the presence of a constituted catalytic system: - on the one hand, as a catalyst, by a solid transition metal compound of the sub-groups iv-a, va and vi-a of the periodic classification of the elements, in which the transition metal is at least part in a state of valence less than maximum, this solid transition metal compound being subjected to a pre-activation treatment by contact with magnesium and one or more monohalogenated hydrocarbons before polymerization, - on the other hand, as co-catalyst, by one or more organometallic compounds of the metals of groups ii and iii of the periodic classification of the elements.
