Process for producing polyolefin |
abstract |
A process for producing a polyolefin is here disclosed which comprises the step of polymerizing olefins in the presence of a catalyst comprising (A) a compound of a transition metal in the group IV of the Periodic Table, (B) an aluminoxane, (C) a compound having 2 or more aromatic rings in its molecule represented by the formula n n n n Ar¹-(YR n-2 ) k -Ar² n n n nwherein the symbols are as defined in the specification, and if necessary, (D) an organic aluminum compound. In this process, the novel catalyst having a high polymerization activity is used, whereby the desired polyolefin can be efficiently produced. |
