<p>The catalyst for polymerizing vinyl compounds according to the present invention comprises (A) a complex of Group 4 to 10 transition metal of the Periodic Table, (B) a clay, clay mineral or ion-exchangeable layered compound, and (C) at least one aluminoxy compound represented by Formula (1): <CHEM> wherein a plurality of R groups are each independently C1-10 hydrocarbon group and at least one of the R groups is a hydrocarbon group having 2 or more carbon atoms; and x is an integer of 2 or more. By using the Group 4 to 10 transition metal complex and the clay, clay mineral or ion-exchangeable layered compound in combination with the specific aluminoxy compound, vinyl polymers are produced at a high efficiency. Also, the catalyst for producing alpha -olefins according to the present invention comprises (A') a complex of Group 8 to 10 transition metal of the Periodic Table, (B') an organic compound-modified clay, clay mineral or ion-exchangeable layered compound, and (C') at least one aluminoxy compound represented by Formula (2): <CHEM> wherein a plurality of R groups are each independently C1-10 hydrocarbon group and at least one of the R groups is a hydrocarbon group having 2 or more carbon atoms; and y is an integer of 2 to 4. Since the organic compound-modified clay, clay mineral or ion-exchangeable layered compound absorbs other catalyst components between layers thereof, the elution of the catalyst components into liquid phase is effectively prevented, thereby facilitating the separation of the catalyst from a reaction product.</p> |
