Abstract:
A carrier for olefin polymerization catalysts, which comprises:i) an aluminum-oxy compound prepared by reacting an organoaluminum compound with water and formulating the material obtained as a solution with a solvent, and removing the solvent from the solution thereby resulting in an aluminum-oxy compound as a dry solid that is then solubilized in a hydrocarbon solvent from which insoluble matter that separates from solution is removed thereby resulting in a solution of aluminum-oxy compound in which the amount of the organoaluminum compound remaining is at most 10% by weight as measured by 1Hâ€”NMR; and ii) an inorganic compound which is a compound of at least one element selected from the group consisting of Groups 2 to 4 and Groups 12 to 14 of the Periodic Table.
