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.
