ABSTRACT OF THE DISCLOSURE The invention relates to a graft polymer comprising an oil-soluble, substantially linear, carbon-carbon backbone polymer having bonded thereto (i) first graft units derived from a first monomer amine containing a polymerizable, ethylenically unsaturated double bond and (ii) second units derived from a second monomer containing at least one of nitrogen, sulfur, or oxygen in a heterocylic ring compound. The polymers are useful to improve the properties of fuel oils and lubricants. The polymers include, for example, ethylene-propylene copolymers bearing units derived from N-vinyl pyrrolidone and phenothiazine.
