PROBLEM TO BE SOLVED: To obtain a new catalyst for producing polyolefin capable of producing poly-α-olefin having high stereoregularity by allowing to comprise a new organic metal polymer in which a metal is coordinated to an organic polymer which binds metallocene ligands to the main chain. SOLUTION: This new catalyst for producing polyolefin comprises an organic metal polymer expressed by the formula, -[O-M<1> R<1> R<2> M<2> X2 ]n - (M<1> is a typical element of IVB group in the periodic table; R<1> and R<2> are each a cyclopentadienyl, indenyl, etc.; M<2> is a transition metal element of IVA group in the periodic table; X is a halogen; (n) is 4-18). The polymer can be preferably obtained by reacting an organic compound of the formula, R<1> R<2> M<1> X2 with water to obtain an organic polymer to which a metal chloride of IV group is reacted. As M<1> in the organic compound of the formula, R<1> R<2> M<1> X2 , a chloride with zirconium is preferable. As a cocatalyst, methylaluminoxane obtained by reacting trimethylaluminum with water can be preferably used. |
