ABSTRACT:
As a flow improver in a crude oil or a liquid hydrocarbon fuel are used polymers containing more than one amide group, the amide being an amide of a secondary amine, and either the amide group or an ester group of the polymer containing a hydrogen- and carbon-containing group of at least 10 carbon atoms, provided that if the polymer is derived from the polymerization of an aliphatic olefin and maleic anhydride, the polymer must have both an amide group and an ester group each of which contains a hydrogen- and carbon-containing group of at least 10 carbon atoms, for example, a diamide of a copolymer of an alkyl fumarate, vinyl acetate and maleic anhydride.
