摘要： A comb polymer can be used for reducing a Noack evaporation loss of a lubricant composition, especially of an engine oil composition. Application of the comb polymer to the lubricant composition can bring about the desired reduction. The comb polymer can include specified amounts of macromonomer and alkyl acrylates. Resulting lubricant compositions can include the comb polymer.

摘要： 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.
