Abstract
The present invention provides a compound comprising the reaction product of a hydrcarbyl substituted amine with an itaconate, such as an N-substituted 4-carboxypyrrolidin-2-one, and methods of employing the same in lubricating compositions. The lubricating compositions containing the N-substituted 4-carboxypyrrolidin-2-one are preferably intended to be employed in a method for lubricating a mechanical device, such as an automatic or manual transmission. However, it is envisioned that the compound can be employed in engine oil lubricants and any other type of functional fluid.
