Abstract of the Disclosure A catalyst for polymerization of an olefin is provided which comprises a solid catalyst component (A) derived by supporting a transition metal compound represented by the general formula (1): Image (1) onto a solid inorganic compound, and then washing the solid inorganic compound with a nonaqueous solvent capable of dissolving the transition metal compound, where M is a transition metal of Group 4b; X1 and X 2are independently a halogen, hydrogen, an alkylalkoxy group, or a saturated or unsaturated alkyl group; R1, R2, R3 and R4 are independently hydrogen or a saturated or unsaturated alkyl group of 1 to 100 carbons; 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): Image (2) - 25 - where ?, is an integer of 2 to 100, R5 is an alkyl group of 1 to 6 carbons, Image (3) where ?' is an integer of 2 to 100, R6 is an alkyl group of 1 to 6 carbons. A process for producing an olefin polymer was also provided in which the aforementioned catalyst is employed. This catalyst is prepared with less amount of organic aluminoxane, yet has high activity. - 26 -
