    摘要: An improved dispersant is prepared by cross-linking a succinimide under Mannich reaction conditions with a polyphenolic compound. The amount of cross-linking, and the resulting size of the reaction product dispersant can be varied by varying the molecular equivalent ratios of succinimide and polyphenol. Lubricating oils containing the dispersant of the reaction product display superior performance.
