ABSTRACT:
Process for the preparation of copolymers consisting of 25-85% by wt. of ethylene, 15-75% by wt. of at least one other 1-alkene and optionally up to 20% by wt. of a polyunsaturated compound with application of a catalyst system containing a compound of a metal from sub-groups IV-VI of the periodic system and a compound of a metal from groups I-III of the periodic system, in which at least one hydrocarbon group is bound directly to the metal atom via a carbon atom, the polymerization being carried out in the presence of certain halogen containing activators.
