Abstract

An olefin polymerization catalyst containing a complex of a ligand being a diimine compound represented by the formula (1) and at least one metal selected from the group consisting of Group 8 elements, Group 9 elements and Group 10 elements:

wherein Ar 1 and Ar 2 are respectively a group represented by the formula (2):

wherein R 1 and R 5 are respectively a hydrogen atom or a hydrocarbyl group having 1 to 5 carbon atoms, the total number of carbon atoms of R 1 and R 3 is 1 or more and 5 or less, and R 2 , R 3 and R 4 are respectively a hydrogen atom or an electron-donating group.

First claim

1 . An olefin polymerization catalyst containing a complex of a ligand being a diimine compound represented by the following formula (1) and at least one metal selected from the group consisting of Group 8 elements, Group 9 elements and Group 10 elements:

wherein Ar 1 and Ar 2 may be the same or different and are respectively a group represented by the following formula (2):

wherein R 1 and R 5 may be the same or different and are respectively a hydrogen atom or a hydrocarbyl group having 1 to 5 carbon atoms, the total number of carbon atoms of R 1 and R 5 is 1 or more and 5 or less, and R 2 , R 3 and R 4 may be the same or different and are respectively a hydrogen atom or an electron-donating group.

2 . The olefin polymerization catalyst according to claim 1 , further containing an organoaluminum compound.

3 . A method for producing an olefin oligomer comprising a step of oligomerizing a polymerizable monomer including an olefin in the presence of the olefin polymerization catalyst according to claim 1 .

4 . A method for producing an olefin oligomer comprising a step of oligomerizing a polymerizable monomer including an olefin in the presence of the olefin polymerization catalyst according to claim 2 .
