Estimating the term…
The present invention relates to a solid catalyst composed of a specific solid catalyst component [A-1], the catalyst containing the solid catalyst and the olefin polymerization process using the solid catalyst, in which the solid catalyst component [A-1] comprises; (a-1) a particulate carrier composed of a specific oxide of a metal; (a-2) an organoaluminum oxy compound; and (a-3) a specific transition metal compound containing a specific ligand, wherein the organoaluminum oxy compound (a-2) and the transition metal compound (a-3) are supported on the particulate carrier (a-1). The catalysts are applicable to a suspension polymerization and a vapor phase polymerization, and capable of preparing spherical olefin polymers excellent in particle characteristics at high polymerization activity.
