Abstract:
A process for polymerizing an olefin, comprising polymerization or copolymerization of olefins in the presence of an olefin polymerization catalyst comprising:(A'"") a transition metal amide compound represented by general formula (IV) below(R.sub.2 N).sub.k M.sup.2 X.sup.2.sub.j-k (IV)where M.sup.2 represents a transition metal atom of Groups 3 to 6 of the Periodic Table, j is the valency of the transition metal atom M.sup.2, k is an integer of 1 to j, each R may be the same or different and represents a hydrogen atom, a hydrocarbon group, a halogenated hydrocarbon group, an organosilyl group or a substituent with at least one element selected from the group consisting of nitrogen, oxygen, phosphorus, sulfur and silicon, the groups represented by R may be linked together to form a ring, when k is 2 or greater, two R groups bonded to different nitrogen atoms may be bonded together to form a bonding group which bonds the 2 nitrogen atoms, X.sup.2 represents a hydrogen or halogen atom, a hydrocarbon group of 1 to 20 carbon atoms, a halogenated hydrocarbon group of 1 to 20 carbon atoms or an oxygen-containing group, sulfur-containing group or silicon-containing group, and when j-k is 2 or greater, each X.sup.2 may be the same or different; and(B-1) an organoaluminum oxy-compound,wherein said organoaluminum oxy-compound (B-1) is added to the polymerization system in a form of an aliphatic hydrocarbon or alicyclic hydrocarbon slurry.
