Catalysts for polymerization or copolymerization of alpha-olefins, catalyst components thereof, and processes for polymerization of alpha-olefins with the catalysts

摘要

The invention has an object to provide a catalyst for polymerizing or copolymerizing an α-olefin, catalyst constituent thereof, and method of polymerizing α-olefins with the catalyst, for production of α-olefin polymers or copolymers with high hydrogen response, high polymarization reaction rate, high stereoregularity and excellent melt fluidity. The invention discloses a catalyst constituent of the catalyst for polymerizing or copolymerizing an α-olefin, represented by Formula 37 or 38: Si(OR¹)₃(NR²R³)  Formula 37 (where in Formula 37, R¹ is a hydrocarbon group with 1 to 6 carbon atoms; R² is a hydrocarbon group with 1 to 12 carbon atoms or hydrogen; and R³ is a hydrocarbon group with 1 to 12 carbon atoms) RNSi(OR¹)₃  Formula 38 (where in Formula 38, R¹ is a hydrocarbon group with 1 to 6 carbon atoms; and RN is a cyclicl amino group).
