Abstract
A method for producing an olefin polymer including: polymerizing one or more α-olefins each having 6 to 20 carbon atoms in the presence of a metallocene catalyst to obtain an olefin polymer, and diluting a polymerization reaction liquid with a solvent before or simultaneously with deactivation of the catalyst, thereby to lower the liquid viscosity of the polymerization reaction liquid to 10 mPa·s or less to promote deactivation and decalcification of the catalyst.
