ABSTRACT:
Coupled polyamine additives for lubricants, fuels and functional fluids have been discovered. The coupled polyamines are prepared by the cyclization reaction of at least one reactant polyamine reactant with at least one hydrocarbyl polynitrile. This coupled polyamine may be further reacted with a hydrocarbyl carboxylic acid or derivative thereof, a hydrocarbyl phenolic reactant or mixtures thereof to provide an additive having greater oil solubility as well as imparting disperancy and VI improvement.
