Abstract

Polyalkyl(meth)acrylate (PAMA) polymers comprising a certain amount of hydroxyl-functionalized alkyl (meth)acrylates can be used for improving the demulsibility performance of high VI lubricating oil compositions. The lubricating oil compositions can be those which are based on apolar base oils, especially hydraulic fluid compositions. The polymers can be comprised in certain lubricating oil compositions.
