Abstract

See full text

Polyalkyl(meth)acrylate based polymers which include straight chained C18-24 alkyl(meth)acrylates and have an average carbon number of 7.0 to 7.5 and a weight-average molecular weight of 300,000 g/mol or greater are a useful component for a lubricant composition. Furthermore, lubricant compositions containing such polymers show improved high temperature-high shear performance, especially in engine oil (EO) compositions.
