摘要： A polyalkyl(meth)acrylate copolymer obtainable by polymerising a monomer composition comprising: (A) from about 5 to about 60 weight percent of a C11-C15 alkyl(meth)acrylate; and (B) from about 95 to about 40 weight percent of a C16-C30 alkyl(meth)acrylate    is effective as a pour point depressant and can also improve the low temperature viscosity of an oil of lubricating viscosity.

摘要： Polyalkyl (meth) acrylate copolymers comprising from about 12 to about 18 weight percent methyl methacrylate; from about 75 to about 85 weight percent of a C 10 -C 15 alkyl (meth) acrylate; and from about 2 to about 5 weight percent of a nitrogen-containing dispersant monomer provide excellent low temperature properties to lubricating oils.
