A random copolymer suitable for reducing friction in lubricant compositions is disclosed. The random copolymer can include a short chain acrylate, a long chain acrylate, and a polar acrylate. The random copolymer can have a ratio of short chain acrylate to long chain acrylate of 0 to 2, and a molecular weight number of 1000 to 10000. The disclosure can include a lubricant containing a base oil and the random copolymer. A process for preparing the random copolymer and polymeric friction modifiers is also disclosed.
