ABSTRACT:
This invention relates to novel compositions of matter, fullerene graft amine-containing polymers, and the process of making them. The graft is made by reacting a fullerene with a primary or secondary amine-containing polymer, preferably a hydrocarbon containing polymer in effective amounts, typically from about 10:1 to about 1:10 mole ratio of reactive amine in polymer to fullerene for a time and under conditions effective to produce the compositions. Suitable starting polymers are those containing primary or secondary amino groups, e.g., EPDM amine, PIB-amine, PIBSA-PAM, and Mannich based polymers. The preferred polymers are oil soluble, as the novel compositions of that type may be used as viscosity modifiers and lube additives. The crosslinked compositions may be used in essentially any application as the original polymer, but in which an increase in tensile strength would be desired.
