METHOD FOR PRODUCING TRIALKYL ALUMINIUM COMPOUND CONTAINING SMALL AMOUNT OF (ALKYL) ALUMINIUM HYDRIDE

摘要

PROBLEM TO BE SOLVED: To obtain a highly purified trialkyl aluminum compound to remarkably improve catalytic activity of a catalyst for olefin polymerization. SOLUTION: Trialkyl aluminum compound containing an (alkyl) aluminum hydride in the concentration of less than 0.1 mass % is obtained by reacting a trialkyl aluminum containing the (alkyl) aluminum hydride of more than 0.1 mass % based on the trialkyl aluminum with olefin, wherein the amount of the (alkyl) aluminum hydride is converted into the amount of aluminum trihydride.
