SPECIFIED C -CARBOXYLATE/VINYL ESTER POLYMER-CONTAINING COMPOSITIONS FOR LUBRICATING OIL FLOW IMPROVEMENT

摘要

Compositions are disclosed for improving at least the low temperature flow properties of lubricating oils. The compositions are dual additives including a first component which is a polymer or interpolymer of a C14 carboxylate, such as a C14-dialkyl fumarate/vinyl acetate interpolymer, and a second component which is a lubricating oil flow improver comprising a non-ethylene containing polymer or interpolymer such as dialkyl fumarate/vinyl acetate interpolymer, esterified styrene/maleic anhydride interpolymer, or esterified olefin/maleic anhydride interpolymer.
