Abstract
Abstract The present invention provides an olefin polymerization solid catalyst prepared by pre-polymerizing olefin in a suspension containing [A] a component obtainable by bringing a particulate carrier, an organoaluminum compound [A-a] and water into contact with one another, [B] a transition metal compound containing a ligand having a cycloalkadienyl skeleton and, if necessary, [c] an organoaluminum compound.
