Abstract

Inventia se refera la un procedeu de obtinere a unui sistem catalitic pentru polimerizarea de alfa-olefine. Sistemul catalitic contine: a) o componenta pe baza de un compus organic de aluminiu, de pilda, trietilaluminiu; b) o componenta continînd triclorura de titan. Componenta continînd halogenura de titan se obtine prin copulverizarea unui compus de magneziu continînd halogen, de pilda, MgCl2, cu un compus donor de electroni, de pilda, benzoat de etil, obtinîndu-se un produs copulverizat. Produsul copulverizat se lasa apoi sa reactioneze cu fosfit organic, de pilda, trifenilfosfit si, în continuare, tetraclorura de titan.
