ABSTRACT OF THE DISCLOSURE Animated polymers, resulting the reaction of a hydrocarbon polymer with an oxygen-containing gas and an amine at temperatures of from about 130°C. provide a multi-functional additive for lubricants and hydrocarbon fu? This reaction can be carried out if desired in an oil solution. The resulting aminated polymers are useful as sludge dispersants for fuels and lubricants. When the aminated polymers have high molecular weight, they are also useful as viscosity-index improvers with dispersant and/or pour point depressant activity.
