A middle distillate fuel composition containing thermally-stabilized middle distillate containing a hydrocarbon boiling in the middle distillate boiling range, an extending vegetable oil and a thermal-stabilizing amount of a nitrogen-containing polymer prepared by sequentially reacting an ethylene/propylene copolymer with maleic anhydride, an alcohol and dimethylaminopropylamine, thereby forming a nitrogen-containing copolymer.

Thermal stabilized vegetable oil extended diesel fuels

Acrylate graft copolymers prepared in a two-stage process by first reacting a backbone polymer, such as 1,2-polybutadiene, an alkylidene norbornene polymer or an ethylene/propylene/alkylidene norbornene terpolymer, with, for example, a mixture of dinitrogen tetroxide and oxygen to form a nitrooxidized polymer having incorporated therein nitro and peroxy nitrate functions which serve, in the second stage of the process, as sites for the subsequent graft polymerization of an acrylate monomer are disclosed. The thus-formed graft copolymers comprise from about 5 to about 80 weight percent of the backbone polymer with the balance being furnished by the acrylate monomer.

Lubricating compositions exhibiting an improved viscosity index are prepared by adding to a lubricating oil base stock a small amount of graft copolymer of a methacrylate ester and an ethylene/propylene/alkylidene norbornene terpolymer.

Lube oil, characterized by improved properties, may be prepared containing polymers having pendant N-hydrocarbylcarboxamide groups -- typically N-(N',N'-dihydrocarbylaminohydrocarbyl) carboxamide groups.
