Abstract
A process for polymerizing .alpha.-olefins in the liquid phase is disclosed, wherein the olefins are polymerized in the presence of a catalyst prepared by first reacting as aluminum-halogen compound with an organomagnesium compound and thereafter reacting the resulting reaction mixture with a transition metal compound and then activating the resulting catalyst system with an organo-aluminum compound. The homopolymers and copolymers of .alpha.-olefins produced by this process find use in the normal applications of such polymers.
