Abstract

This disclosure relates to a composition for use as an additive for fuels and lubricants including a reductive amination product of a vinyl terminated macromonomer (VTM) based aldehyde. Optionally aldehyde is reacted with the amino compound under condensation conditions sufficient to give an imine intermediate, and the imine intermediate is reacted under hydrogenation conditions sufficient to give the composition. The aldehyde is formed by reacting a VTM under hydroformylation conditions sufficient to form the aldehyde. A reductive amination method for making a composition for use as an additive for fuels and lubricants. The method includes reacting a VTM based aldehyde with an amino compound containing at least one —NH— group under condensation conditions sufficient to give an imine intermediate, and reacting the imine intermediate under hydrogenation conditions sufficient to give said composition. The aldehyde is formed by reacting a VTM under hydroformylation conditions sufficient to form the aldehyde.
