Abstract:
A process for producing a polymer comprising one or more &agr;-olefins, said process comprisingpolymerizing one or more &agr;-olefins having at least 4 carbon atoms in the presence of a catalyst, said catalyst comprising: (A) at least one compound represented by formula (I): whereinR1 to R6 and X1 to X2 each independently represent a hydrogen atom, a halogen atom, a hydrocarbon group having 1 to 20 carbon atoms, a hydrocarbon group having 1 to 20 carbon atoms and a halogen atom, a group having silicon, a group having oxygen, a group having sulfur, a group having nitrogen or a group having phosphorus; adjacent groups among groups represented by R1 to R6 and X1 to X2 may form a ring by forming bonds between each other; Y1 to Y2 each independently represent a divalent group which forms a bond between two ligands and is selected from the group consisting of hydrocarbon groups having 1 to 20 carbon atoms, hydrocarbon groups having 1 to 20 carbon atoms and a halogen atom, a group having silicon, a group having germanium, a group having tin, â€”Oâ€”, â€”COâ€”, â€”Sâ€”, â€”SO2â€”, â€”NR13â€”, â€”PR13â€”, â€”P(O)R13â€”, â€”BR13â€” and â€”AlR13â€”; R13 representing a hydrogen atom, a halogen atom, a hydrocarbon group having 1 to 20 carbon atoms or a hydrocarbon group having 1 to 20 carbon atoms and a halogen atom, and M1 represents a transition metal of Groups 4 to 6 of the Periodic Table; and (B) at least one compound selected from (b-1) organoaluminum oxy compounds and (b-2) ionic compounds which can be converted into cations by reaction with the transition metal compounds of component (A), and hydrogenating the polymer.
