摘要
This invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity and a minor amount of a salt of at least one nitrogen containing polyacrylate and at least one phosphorus acid ester. The invention also relates to lubricating compositions and concentrates containing the same. The present phosphorus salts of the nitrogen containing copolymers provide improved dispersant, viscosity improver and antiwear properties to lubricating compositions.
