Polyethylene diester viscosity modifiers

摘要

Disclosed are compositions containing at least one of the following:(1) estolide polyethylene glycol diesters;(2) hydroxy derived estolide polyethylene glycol diesters;(3) unsaturated hydroxy derived estolide polyethylene glycol diesters;(4) estolide trimetholpropane diesters;(5) hydroxy derived estolide trimetholpropane diesters;(6) unsaturated hydroxy derived estolide trimetholpropane diesters;(7) estolide epoxide polyethylene glycol diesters;(8) estolide dihydroxide polyethylene glycol diesters;(9) mono-capped hydroxy derived estolide epoxide polyethylene glycol diesters;(10) mono-capped hydroxy derived estolide dihydroxide polyethylene glycol diesters;and mixtures thereof; and optionally a carrier. All the compounds can be used as a viscosity index improver thereby improving a lubricant's performance.
