Dispergeta poli(met)akrilata viskozitates raditaja uzlabotaji

摘要

This invention is concerned with copolymers derived from (a) one or more monomer selected from (C1-C24)alkyl methacrylates and (C1-C24)alkyl acrylates, and (b) one or more monomer selected from hydroxy(C2-C6)alkyl methacrylates and hydroxy(C2-C6)alkyl acrylates, and wherein the number of carbon atoms in the alkyl groups averages from about 7 to about 12. These polymers are useful as additives to lubricating oils for providing viscosity index improvement, dispersancy and low temperature fluidity properties without adversely affecting fluoropolymer seals and gaskets.
