Abstract

Procedeul de obtinere a homo si copolimerilor etilenei prin polimerizarea în suspensie, caracterizat prin aceea ca în mediul de reactie se introduce un catalizator constînd din compusi de titan pe un suport cu formula generala RMgCl. nAlCl3, în careR reprezinta un radical alchil C4-C10, n este 0,005...0,3 si un compus aluminoorganic, compusul de titan fiind o combinatie de tetraalcoxititan cu tetraclorura de titan în raport molar de 0,1:1...3:1, continutul de titan în catalizator fiind 2,1...5,8% masa, polimerizarea conducîndu-se în prezenta a 25...30% volum hidrogen.
