PROBLEM TO BE SOLVED: To polymerize an olefin without using an arom. hydrocarbon and without being accompanied by fouling, by combining a metallocene compd. solubilized by the contact with an organometallic compd. in an aliph. hydrocarbon with a cocatalyst carried by a fine particulate carrier. SOLUTION: The aliph. hydrocarbon may be alicyclic. Examples of the organometallic compd. are organoaluminum (except aluminoxanes), organolithium, organozinc, and organomagnesium compds. An example of the metallocene compd. is bis(η<5> -cyclopentadienyl)zirconium dichloride. The amt. of the organometallic compd. mixed with the metallocene compd. is 10-800 times that of the transition metal atom of the metallocene compd. The cocatalyst, e.g. methylaluminoxane, is carried by a fine paticulate carrier such as silica or alumina.
