Abstract: Oxidized polyisobutenes, that is polyisobutenes containing ketonic and carboxylic acid carbonyl groups, are produced by passing through a column of the polyisobutene maintained at a temperature in the range from 140.degree. to 200.degree. C. and at atmospheric or elevated total pressure a molecular oxygen-containing gaseous oxidant at a gas flow rate greater than 10 liters cm.sup.-2 h.sup.-1 measured at the operating pressure. The oxidized polyisobutenes can be reacted for example with an aliphatic polyamine to produce a lubricating oil additive or with an aliphatic polyamine and formaldehyde to produce a fuels additive.

Abstract: This invention is to lubricating or fuel oil compositions containing amine compatibility aids.The amine compatibility additives are especially useful in stabilizing (or "compatibilizing") concentrates, lubricating oil or fuel oil compositions which contain copper antioxidants, high molecular weight dispersants, high total base number detergents, and various antiwear friction modifier materials. These materials may, in some circumstances, replace at least a portion of previously used compatibility aids and antioxidants.
