Olefin polymerization solid catalyst, olefin polymerization catalyst and olefin polymerization.

摘要

The invention relates to a solid catalyst component (A-1) of a catalyst for use in the polymerization of at least one olefin and comprising (a-1) a particulate carrier composed of a specific oxide of a metal, and supported on the carrier, (a-2) an organoaluminum oxy compound and (a-3) a specific transition metal compound containing a specific ligand. The catalyst component can be used, optionally in conjunction with an organoaluminum compound, in the suspension polymerization or vapor phase polymerization of at least one olefin to provide spherical olefin polymers having excellent particle characteristics at high polymerization activity.
