SUPPORTED CATALYTIC SYSTEM FOR THE PRODUCTION OF ETHYLENE PROPYLENE COPOLYMERS |
摘要 |
Catalytic component for the polymerization of ethylene with propylene prepared by: a) impregnation of an inert support with a solution of a compound of Vanadium having an oxidation state of between 3 and 5; b) subsequent treatment with a solution of a compound having general formula (I) RnAlXm wherein R is a C1-C20 alkyl radical, X is a halogen, n + m = 3, and m is an integer between 0 and 2, the molar ratio between Aluminium in step (b) and Vanadium in step (a) being from 1/1 to 6/1.
