Polymerization of olefins in presence of a catalyst prepared from organomagnesium compound, carbon dioxide compound, reducing halide source and transition metal compound

摘要

Olefins or mixtures thereof are polymerized in the presence of the product resulting from heating in an inert hydrocarbon diluent a mixture of (A) an organomagnesium material, (B) essentially anhydrous carbon dioxide, (C) a reducing halide source and (D) a transition metal compound.
