Viscosity index improver, lubricant composition and method for producing lubricant composition |
| abstract |
Provided is a viscosity index improver including a comb-shaped polymer and satisfying the following requirement (I) or (II). n Requirement (I): With respect to a solution having the viscosity index improver dissolved in a mineral oil and having a solid component concentration of 25 mass%, a ratio [(G')/(G")] of a storage modulus (G') to a loss modulus (G") of the solution as measured under prescribed conditions with a measuring temperature of 70°C is 0.40 or more. n Requirement (II): With respect to a solution (α) at 25°C having the viscosity index improver dissolved in a mineral oil and having a solid component concentration of 25 mass% and a solution (β) resulting from subjecting the solution (α) to temperature rise to 100°C at a prescribed temperature rise rate and then cooling to 25°C at a prescribed cooling rate, a ratio of a storage modulus (G') of the solution (β) to a storage modulus (G') of the solution (α) as measured under prescribed conditions with a measuring temperature of 25°C is 2.0 or more. |
