Abstract:
A process for producing an olefin polymer characterized in that olefin polymerization or copolymerization is carried out under the presence of:a catalyst, comprising (A) a compound of a transition metal selected from among groups 3 to 10 of the periodic table with lanthanides and actinides being included in group 3 and (B) at least one compound selected from among (B-1) organoaluminum oxycompounds, (B-2) compounds that react with the abovementioned compound (A) to form an ion pair, and (B-3) organoaluminum compounds and under the coexistence of (C) an organosilicon compound represented by the general formula (1) given below, or (D) a dialkylzinc compound represented by the general formula (II) given below, R1R2R3SiHâ€ƒâ€ƒ(I) â€ƒwherein R1, R2 and R3 may be the same or may differ from each other, with each indicating a hydrogen atom, an alkyl group of 1 to 4 carbon atoms, an aryl group of 6 to 12 carbon atoms, an alkylaryl group of 7 to 20 carbon atoms, an arylalkyl group of 7 to 20 carbon atoms, an alkoxy group of 1 to 4 carbon atoms, a phenoxy group, a fluoroalkyl group of 3 to 6 carbon atoms, a dialkylamino group containing alkyl groups of 1 to 4 carbon atoms, or a diorganopolysiloxane chain containing 1 to 10 siloxane units ZnR4R5â€ƒâ€ƒ(II) â€ƒwherein R4 and R5 may be the same or may differ from each other, with each indicating an alkyl group of 1 to 20 carbon atoms and (E) hydrogen.
