Abstract:
1. A method of producing an α-olefin polymer, comprising: polymerizing one or more α-olefins, each comprising 6 to 14 carbon atoms, with a catalyst obtained by combining components (A) and (B): (A) a transition metal compound of formula (I): where R at least one selected from the group consisting of R at least one selected from the group consisting of R R R X M represents a transition metal belonging to Group 4 of the periodic table; and (B) at least one selected from the group consisting of (b-1) an organic aluminum oxy compound and (b-2) an ionic compound capable of reacting with the above transition metal compound to transform the compound into a cation; wherein reaction conditions in the polymerizing comprise: a hydrogen pressure of 0 to 0.2 MPa (G); and a reaction temperature of 0 to 200° C.; wherein the α-olefin polymer has a kinematic viscosity at 100° C. of 20 to 1,000 mm wherein the α-olefin polymer is an α-olefin polymer whose α-olefin unit sequence portion has an isotacticity of 20 to 40% and a syndiotacticity of 40% or less in terms of triad expression.
