METHOD FOR PRODUCING CYCLIC NON-CONJUGATED DIENE-NICKEL COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a method for easily purifying a cyclic non-conjugated diene-nickel compound producible from a bivalent nickel compound.;SOLUTION: A cyclic non-conjugated nickel compound is produced by reacting a bivalent nickel compound available at a low cost with a cyclic non-conjugated diene and a trialkylaluminum in an aliphatic compound and easily purifying the product by solid-liquid separation. The obtained compound exhibits high activity even by using as a precursor in various reactions such as olefin polymerization reaction, especially polymerization of an olefin in an aqueous system.;COPYRIGHT: (C)2008,JPO&INPIT
