摘要：
Process for the polymerization of ethylene with C 3 -C 10 alpha-olefins in suspension of liquid monomer in the presence of a catalyst containing Vanadium obtained by the precipitation, in an atmosphere of ethylene or alpha-olefins, of:
a) a compound of Vanadium in the oxidation state of 3 to 5, with b) a basically hydrocarbon solution of a compound selected from those having general formula R n AlX m wherein R is a C 1 -C 20 alkyl radical, X is a halogen, m+n = 3 , n is an integer from 0 to 2.
