The invention has an object to provide a catalyst for polymerizing or copolymerizing an alpha -olefin, catalyst constituent thereof, and method of polymerizing alpha -olefins with the catalyst, for production of alpha -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 alpha -olefin, represented by Formula 37 or 38: Formula 37 Si(OR )3(NR R ) (where in Formula 37, R is a hydrocarbon group with 1 to 6 carbon atoms; R is a hydrocarbon group with 1 to 12 carbon atoms or hydrogen; and R is a hydrocarbon group with 1 to 12 carbon atoms) Formula 38 RNSi(OR )3 (where in Formula 38, R is a hydrocarbon group with 1 to 6 carbon atoms; and RN is a cyclicl amino group).
