摘要： A method for producing .alpha.-olefin polymers or copolymers by the use of an improved catalyst having a specific solid product combined with an organoaluminum compound is provided.The specific solid product (III) is prepared byreacting a trivalent metal halide with a specified divalent metal compound to obtain a solid product (I);reacting this product (I) with a transition metal compound of 4a group or 5a group of the Periodic Table in the presence of a polysiloxane to obtain a solid product (II); andfurther reacting this product (II) with at least two transition metal compounds of 4a group or 5a group, consisting of at least one member selected from the group (A) consisting of halogen-containing transition metal compounds of 4a group or 5a group, and at least one member selected from the group (B) consisting of halogen-free transition metal compounds of 4a group or 5a group to obtain the solid product (III).By employing this improved solid product (III) as a catalyst component, it is possible to produce .alpha.-olefin polymers or copolymers having a broader molecular weight distribution with a high polymer yield.
