Dispersing agent for lubricating oil, method for producing same, and lubricating oil composition |
| abstract |
A dispersant for a lubricating oil, containing at least one compound selected from a specific nitrogen-containing compound which is obtained by using, as raw materials, (A) at least one polyolefin selected from polybutene and polyisobutene, (B) at least one maleic acid compound selected from maleic acid and maleic anhydride, and (C) polyamine; a boride of the specific nitrogen-containing compound; and an acylated product of the specific nitrogen-containing compound. The polyolefin (A) satisfies at least one of the following conditions (α) and (β). (α) a ratio (Sb/Sa) of an integrated value (Sb) of a peak present at 4.40 to 5.00 ppm in a 1 H-NMR spectrum to an integrated value (Sa) of a peak present at 5.01 to 5.60 ppm in the 1H-NMR spectrum is 2 or more. (β) a ratio (Sd/Sc) of an integrated value (Sd) of a peak present at 1.76 to 2.10 ppm in the 1H-NMR spectrum to an integrated value (Sc) of a peak present at 1.65 to 1.75 ppm in the 1 H-NMR spectrum is 1 or more. |
