ABSTRACT:
This invention relates to novel compositions of matter that are lube oils comprising an oil/hydrocarbon soluble fullerene grafted amine-containing polymers and a suitable base oil and, optionally other suitable additives for use as a lubricating oil. This invention also relates to the method of using the fullerene grafted amine-containing polymer itself as additives to base oils. The graft is made by reacting a fullerene with a primary or secondary amine-containing polymer, preferably hydrocarbon containing polymers. Suitable starting polymers are those containing primary or secondary amino groups, e.g., EPDM amine, PIB-amine, PIBSA-PAM, and Mannich based polymers. The lube oil compositions are made by adding an effective amount of the polymer, and optionally, other suitable additives to a base oil typically on an active ingredient basis of from about 0.01 to about 20 wt. %.
