ABSTRACT:
A urethane reaction product, derived from an alkoxylated diorgano phosphorodithioate and an isocyanate, specifically, toluenediisocyanate and hexamethylene diisocyanate, is a multifunctional antiwear and antioxidant additive for lubricants. The isocyanate groups of the reaction product are substantially converted to urethane and/or urea groups through post reaction with active hydrogen compounds such as dibutylamine, bis(2-hydroxethyl) cocoamine and alcohols such as 2-propanol.
