Diraromatic amine derivatives having the general formula: wherein n is from 0 to 5; m is from 0 to 4; each R substituent is independently hydrogen or a straight or branched C1-C32 alkyl group or alkenyl group or two R substituents together with the carbon atom to which they are bonded are joined together to form an unsaturated, partially saturated or saturated C3-C30 ring structure optionally containing one or more heteroatoms, each R<1 >substituent is independently hydrogen or a straight or branched C1-C32 alkyl group or alkenyl group and R<2>, R<3>, R<4>, R<5>, R<6 >and R<7 >are independently hydrogen or a straight or branched C1-C32 alkyl group or alkenyl group optionally containing a functional group are provided. Also provided are lubricating oil compositions containing the diraromatic amine derivatives. |
