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 aims at providing catalysts for the polymerization or copolymerization of alpha-olefins which exhibit high hydrogen response and high polymerization activity and can give polymers and copolymers of alpha-olefins having high stereoregularity and excellent melt flow characteristics; catalyst components of the catalysts; and processes for the polymerization of alpha-olefins with the catalysts. The invention relates to catalyst components of the catalyst for the polymerization or copolymerization of alpha-olefins which are represented by the general formula (37) or (38) : Si(OR1)3(NR2R3) (37) (wherein R 1 is hydrocarbyl having 1 to 6 carbon atoms; R2 is hydrocarbyl having 1 to 12 carbon atoms or hydrogen; and R3 is hydrocarbyl having 1 to 12 carbon atoms), and RNSi(OR1)3 (38) (wherein R1is hydrocarbyl having 1 to 6 carbon atoms; and RN is cyclic amino).
