Abstract

The use is described of polymers which contain, in copolymerized form, an α-olefin, a vinyl ester and an ester of an α,β-unsaturated carboxylic acid as an additive for fuel oils and lubricants and in particular as a cold flow improver in fuel oils. In addition, the fuel oils and lubricants additized with these polymers; and also additive packages comprising such polymers are described.
