Abstract
Inventia de fata se refera la un catalizator pentru polimerizarea alfa-olefinelor, constituit dintr-un suport de halogenura de magneziu impregnat cu TiCl4 si un cocatalizator constituit dintr-o monohalogenura de dialchilaluminiu asociata cu monohalogenura de trialchilaluminiu. Se obtine o îmbunatatire a activitatii catalizatorului, precum si a indicelui de izotacticitate a polimerului.
