<p>A catalyst for the polymerization of olefins is provided which comprises a solid catalyst component (A) derived by supporting a transition metal compound represented by the general formula (1): <CHEM> onto a solid inorganic compound, and then washing the solid inorganic compound with a nonaqueous solvent capable of dissolving the transition metal compound, wherein M is a transition metal of Group 4b; X<1> and X<2> are independently a halogen, hydrogen, an alkylalkoxy group, or a saturated or unsaturated alkyl group which groups may be linked together to form a bond; R<1>, R<2>, R<3> and R<4> are independently hydrogen or a saturated or unsaturated alkyl group of 1 to 100 carbon atoms which groups may be linked together to form a bond; m is an integer of 1 to 6; and p and q are independently an integer of 0 to 4, and a catalyst component (B) comprising an organic aluminum compound represented by the general formula (2) and/or (3): <CHEM> wherein l is an integer of 2 to 100, R<5> is a saturated or unsaturated alkyl group of 1 to 6 carbons, <CHEM> wherein l ' is an integer of 2 to 100, R<6> is a saturated or unsaturated alkyl group of 1 to 6 carbons. A process for producing olefin polymers was also provided in which the aforementioned catalyst is employed. This catalyst is prepared with less amount of organic aluminoxane, yet has high activity.</p> |
