Document Type and Number:
Japanese Patent JP6703453
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a viscosity index improver composition excellent in shear stability of a lubricant composition, low in HTHS viscosity of the lubricant composition, hard to increase low temperature viscosity of the lubricant composition and easy to handle under ambient temperature.SOLUTION: There is provided a viscosity index improver composition containing a polymer (A) with a monomer (a) represented by the general formula (1) as a constitutional unit and a base oil and having a value (V1) of 40°C kinetic viscosity divided by 100°C kinetic viscosity in a range of 0.2 to 5.SELECTED DRAWING: None
