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 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(OR1)3(NR2R3) (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) Formula 38 RNSi(OR1)3 (where in Formula 38, R1 is a hydrocarbon group with 1 to 6 carbon atoms; and RN is a cyclicl amino group).
