A method is described for improving the viscosity storage stability of a Mannich base condensation product of an oxidized polyolefin, formaldehyde, and an amine. This method involves contacting such Mannich base condensation product with a lower alkyl peroxide, a lower alkyl hydroperoxide or an aryl(lower)alkyl hydroperoxide at a temperature of about 250.degree. F. to about 400.degree. F. for a time period sufficient to provide an oxidized product.

Increasing viscosity storage stabiity of Mannich base

Improved dispersant and VI-improving Mannich composition having reduced susceptibility to viscosity increase during storage, which composition comprises a physical blend prepared by admixing a phenolic compound with a Mannich condensation product obtained from the Mannich reaction of an oxidized polymer, an amine and a formaldehyde-yielding reagent.

Mannich dispersant VI-improver blended with phenolic compound for

Polyborate ester compositions are prepared by reacting ortho-boric acid with at least one alcohol or phenol in a substantially inert organic liquid, which is immiscible with water and has a boiling point in the range from about 80.degree. to about 300.degree. C. at standard pressure, and by continuously removing the water which is produced by the reaction.

Polyborate esters and their use in lubricants

Molybdenum compositions suitable for improving the properties of lubricants and fuels comprise the reaction product of molybdenum and a polyamine Mannich reaction product, a polyamine hydrocarbyl-substituted dicarboxylic acid compound reaction product, and the oxidized and/or sulfurized reaction products thereof.

A transamination process for producing Mannich products comprising reacting a polyamine with a substantially formaldehyde-free mononitrogen Mannich adduct.

Transamination process for Mannich products

Crude oils and residual fuel oils having improved pour point and flow properties are obtained by incorporating therein a small amount of a new terpolymer prepared from ethylene, a vinyl ester, and a dialkylvinyl carbinol. The terpolymer has a number average molecular weight of about 500-10,000 and suitably contains 45-80 wt. % ethylene, 10-25 wt. % vinyl ester of a fatty acid having up to about eight carbon atoms and 10-30 wt. % dialkylvinyl carbinol wherein the alkyl groups have up to about six carbon atoms.
