Polymeric dispersants and method of making same |
| abstract |
This invention concerns the utilization of polymeric compounds generated from Mannich base macromonomers as lubricant oil and fuel additives or intermediates to such additives. Requisite macromonomers are generated via Mannich reaction of high molecular weight alkyl phenols and unsaturated amines. Homopolymers of the Mannich base macromonomers or copolymers with activated unsaturated monomers, such as maleic anhydride, are of particular interest as crankcase dispersants. For example, functionalization of Mannich base macromonomer/maleic anhydride copolymers with amines affords effective crankcase dispersants. Such polymeric dispersants are designed to impart superior sludge protection and improved viscometrics to lubricant oils. |
