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; deactivating and decalcifying the catalyst to obtain a decalcified polymerization reaction liquid; mixing the decalcified polymerization reaction liquid containing the olefin polymer with water; and washing the liquid with stirring at a stirring intensity of 0.1 kW/m3 or more for 1 minute or longer.
