Japanese Patent JPS51107303
Kind Code:
A
Abstract:
Aminated polymers, resulting from the reaction of a hydrocarbon polymer with an oxygen-containing gas and an amine compound at elevated temperatures of from about 130 DEG C. to about 300 DEG C. provide a multi-functional additive for lubricants and hydrocarbon fuels. This reaction can be carried out if desired in an oil solution. The resulting aminated polymers are useful as sludge dispersants for fuel lubricants. When the aminated polymers have a high molecular weight, they are also useful as viscosity-index improvers with dispersant and/or pour point depressant activity.
