Abstract
Process for obtaining polyethylene of narrow molecular weight distribution, of very small proportion of low molecular weight and of improved mechanical values, characterized by polymerizing ethylene by catalysts obtained starting from esters of vanadic acid of the general formula ** (See formula) ** where R represents a lower aliphatic moiety with 1-8 C atoms, and aluminum alkyl halides, the alkyl moiety may also contain 1-8 C atoms, and where halogen may represent chlorine, bromine or iodine.
