Abstract
A process for the continuous manufacture of homopolymers of an ethylene monomer and copolymers of an ethylene monomer with at least one .alpha.-olefin containing 3 to 8 carbon atoms. The monomers and a catalytic system are introduced into a first stage reactor to form a reaction medium for polymerizing the monomers. During a first stage, when the polymerization is substantially complete, a first compound, which is capable of reducing a transition metal of the catalytic system, is introduced into the reaction medium.
