ABSTRACT:
An antioxidant, dispersant lubricating composition comprises the product produced by first reacting an alkyl acrylate with an amine to produce an intermediate product, a first generation polyamine ester dendrimer which is then treated with an amine to produce a first generation polyamidoamine dendrimer which is then reacted with an acrylate to produce a second generation polyamidoamine ester dendrimer which with an amine is converted to a second generation polyamidoamine dendrimer which is then reacted with a polyisobutenyl succinic acid anhydride to produce the reactant product a polyisobutenyl succinimide-polyamidoamine dendrimer polymer.
