Abstract

An improved process for the polymerization of a monomer charge comprising ethylene, by contacting said charge with at least one chromium [II] bis (cyclopentadienyl) compound on an inorganic oxide support, said chromium compound [II] having ] -bis (cyclopentadienyl) structure **(See formula)** in which n'and n''are each integers from 0 to 5, inclusive, and R' and R'' are each hydrocarbon radicals from C1 to C20, inclusive and said inorganic oxide has a large surface area being selected from the group consisting of silica, alumina, thorium oxide, zirconium oxide and mixtures thereof, characterized in that it comprises modifying said catalyst, before said contact, with at least one compound having in it its structure at least one group of the formula (see formula) in which the X are the same or different and are C or Si.
