METHOD OF PRODUCING HYDROGENATED α-OLEFIN POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a method capable of producing a hydrogenated α-olefin polymer having good quality and high viscosity, and to provide the hydrogenated α-olefin polymer obtained through the production method.SOLUTION: A method of producing a hydrogenated α-olefin polymer includes: a step (a) of polymerizing an α-olefin to produce a polymerization solution containing an α-olefin polymer having a different polymerization degree; a step (b) of distilling the polymerization solution obtained in the step (a) to obtain an α-olefin polymer whose 100°C kinematic viscosity is 40-300 mm/s inclusive; and a step (c) of hydrogenizing the α-olefin polymer obtained in the step (b) to obtain the hydrogenated α-olefin polymer.
