Abstract: A polymer comprises a polymeric backbone, at least one piperidine ester moiety extending from the polymeric backbone, and generally at least one C8 to C22 ester moiety extending from the polymeric backbone. The polymer is useful for adjusting the total base number and viscosity index of a lubricant composition. The lubricant composition generally comprises a base oil in addition to the polymer. A method of forming the polymer comprises the steps of providing a first component and providing a second component. The first component comprises at least one of A1) a piperidine methacrylate, or A2) a methacrylate. The second component comprises at least one of B) a C8 to C22 methacrylate. Optionally, the method further comprises the step of providing a third component, which comprises at least one of C) a piperidine-ol. The method further comprises at least one reaction step involving the aforementioned components to form the polymer.
