    摘要: Disclosed are a catalyst for olefin polymerization comprising (A) a compound of a transition metal in Group IVB of the periodic table which contains a ligand having a cyclopentadienyl skeleton, (B) an organoaluminum compound and any one of (C1) a Br.o slashed.nsted acid; (C2) a material obtained by contacting (c-1) a magnesium compound with (c-2) an electron donor; and (C3) a material obtained by contacting (c-1) a magnesium compound, (c-2) an electron donor and (c-3) an organometallic compound with each other. Also disclosed are processes for polymerizing an olefin in the presence of the above-mentioned catalysts for olefin polymerization. Such catalysts and processes for olefin polymerization as described above are excellent in olefin polymerization activity and economical efficiency.
