摘要
A novel olefin polymerization catalyst comprising: (A) a transition metal compound comprising a transition metal having eta-bonded thereto a cyclic anionic ligand; (B) a mixture of (B-1) an activator compound capable of forming, together with component (A), a metal complex having a catalytic activity and (B-2) an organometal compound, the activator compound (B-1) comprising a cation and a noncoordinating, compatible anion; (C) a solid component; and optionally (D) an organoaluminum compound, wherein the catalyst is obtained by contacting components (A) to (C) and optionally component (D). The olefin polymerization catalyst of the present invention is advantageous not only in that it has high polymerization activity, but also in that an olefin polymer having excellent powder characteristics can be efficiently produced by suspension polymerization (slurry polymerization) or gaseous phase polymerization in a continuous manner, using a commercial scale plant, while preventing the occurrence of adherence of the polymer to the inside surfaces associated with a polymerizer.
