| titleOfInvention | Olefin block copolymer, viscosity index improver for lubricating oil, and lubricating oil composition |
| abstract | An olefin block copolymer, a viscosity index improver, and a viscosity index improver are provided as a viscosity index improver that provides a lubricating oil composition having excellent low-temperature characteristics and an excellent balance between viscosity and shear stability. Providing a lubricating oil composition comprising. An olefin block copolymer includes (i) a molar ratio of ethylene units to α-olefin units (ethylene / α-olefin) of 40/60 to 64/36, and Mw of 80,000 to 500,000. And (ii) a polymer block having a molar ratio of ethylene units to α-olefin units (ethylene / α-olefin) of 73/27 to 82/18 and Mw of 30,000 to 150,000 And when Mw / Mn is 1.25 or less and pyrolyzed, (i The absolute value of the slope (CD) of the intramolecular composition distribution of the component derived from (ii) and the component derived from (ii) is 0.07 to 0, and (ii) has a weight average molecular weight smaller than (i).
