US 9,315,761 B2 · Lubricant and fuel dispersants and methods of preparation thereof

Abstract

This disclosure relates to a composition for use as an additive for fuels and lubricants including an amination product of an epoxidized vinyl terminated macromonomer (VTM) and an amino compound containing at least one —NH— group. The epoxidized VTM is reacted with the amino compound containing at least one —NH— group under amination conditions sufficient to give said composition. The epoxidized VTM is formed by reacting a VTM with an epoxidizing agent under epoxidation conditions sufficient to give an epoxidized VTM. An amination method for making a composition for use as an additive for fuels and lubricants. The method comprises reacting an epoxidized VTM with an amino compound containing at least one —NH— group under amination conditions sufficient to give the composition. The epoxidized VTM is formed by reacting a VTM with an epoxidizing agent under epoxidation conditions sufficient to give an epoxidized VTM.
