摘要
A method for improving the low temperature fluidity of lubricating oil compositions based on addition to lubricating oils of a mixture of selected high molecular weight and low molecular weight alkyl (meth)acrylate copolymers is disclosed. Combinations of low molecular weight alkyl (meth)acrylate polymers containing zero to 25 weight percent (C16-C24)alkyl (meth)acrylate with high molecular weight alkyl (meth)acrylate polymers containing 25 to 70 weight percent (C16-C24)alkyl (meth)acrylate are especially effective at satisfying different aspects of low temperature fluidity properties simultaneously for a broad range of base oils.
