PRODUCTION OF MANNICH REACTION PRODUCT FROM OXIDIZED POLYMER

摘要

A process for the preparation of oil-soluble Mannich condensation products wherein an amine is prereacted with a sulfonic acid or ammonium sulfonate, oleic acid, and an oxidized olefin polymer and the prereaction product is reacted with an aldehyde. The reaction products can be used as additives particularly as dispersant-viscosity index improvers of lubricating oils.
