Abstract:
Polyalkyl(meth)acrylates contain specified amounts of long-chain alkyl (meth)acrylates and functional monomers. Lubricant compositions can contain such polyalkyl(meth)acrylates, and the polyalkyl(meth)acrylates can be used as viscosity index (VI) improvers with good fuel economy as well as soot-dispersant function. The polyalkyl(meth)acrylates can provide equal or even unproved deposits in lubricant compositions, especially in engine oil (EO) compositions.
