Abstract
This invention provides a process for the oxidation of copolymers of ethylene and olefinic monomers in the temperature range of from about -40.degree. F to about 800.degree. F. The oxidation is carried out in the presence of about 0.05 weight percent to about 1.0 weight percent based on copolymer/oil solution, of an oil soluble benzene sulfonic acid or salt thereof. These benzene sulfonic acids or salts thereof affect the rate of the oxidation reaction and/or the color of the oxidized product or amine reaction products thereof.
