ABSTRACT:
A viscosity index improver, comprising an oil-soluble copolymer (A) having 20-70% by weight of alkyl acrylate units and 30-80% by weight of alkyl methacrylate units, and a viscosity index improver, comprising 20-80% by weight of an oil-soluble alkyl acrylate (co)polymer (A1) and 20-80% by weight of an oil-soluble methacrylate (co)polymer (A2), are capable of reducing high-temperature high-shear viscosity, particularly isoparaffin-containing high viscosity index oil, and provide luburicating oils useful as engine oil, gear lubricant and so on.
