Abstract

PURPOSE: To obtain the title catalyst which can give a polymer of excellent particle properties at high polymerization activity by prepolymerizing an olefin in a suspension or a vapor phase containing a particulate carrier, two specified transition metal compounds and an organoaluminumoxy compound.
CONSTITUTION: The title catalyst is obtained by prepolymerizing an olefin in a suspension or a vapor phase containing a particulate carrier, transition metal compound containing ligands each having a cycloalkadienyl skeleton which are not combined with each other, a transition metal compound containing at least two ligands each having a cycloalkadienyl skeleton at least two of which are bonded to each other through (substituted) alkylene or (substituted) silylene, and an organoaluminumoxy compound. When this catalyst is used in a suspension polymerization process or a vapor phase polymerization process even when it contains a reduced amount of the lost component, it can give a spherical olefin polymer of excellent particle properties with high polymerization activity.
