  • Method for producing olefin polymer
    Patent number: 9382358
    Abstract: A method for producing an olefin polymer including: polymerizing one or more ?-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.
    Type: Grant
    Filed: June 28, 2012
    Date of Patent: July 5, 2016

  • Method for producing olefin polymer
    Patent number: 9056931
    Abstract: A method for producing an olefin polymer including: polymerizing one or more ?-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.

  • Method for producing alpha-olefin oligomer
    Patent number: 8816034
    Abstract: A method for producing an ?-olefin oligomer including: polymerizing in the presence of a catalyst one or more ?-olefins having 6 to 20 carbon atoms to produce an ?-olefin oligomer; and deactivating the catalyst by a deactivator from which oxygen is removed. A method for producing an ?-olefin oligomer including: polymerizing in the presence of a catalyst one or more ?-olefins having 6 to 20 carbon atoms to produce an ?-olefin oligomer; and passing the reaction solution containing the ?-olefin oligomer through a bag filter.
