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 polymerisation 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.
Additives suitable for improving the flow and/or depressing the cloud point of crude oils, lubricating oils and especially fuel oils are polymers containing defined alkyl groups of at least 8 carbon atoms chain length. Such polymers are either (a) of a mixture of monomers having only two alkyl groups one being at least 3 carbon atoms longer than the other or (b) of a mixture of monomers having only three alkyl groups each differing by at least 3 carbon atoms and the middle alkyl group being half the combined length of the other two. Alternatively, the polymer may be derived from a monomer having the two defined alkyl groups (a) or the three defined alkyl groups (b).

A hemolysis inhibitor comprising a polycarboxylic acid ester, an ether compound and/or a monocarboxylic acid ester and a medical resin composition, medical implement, and blood-preserving fluid containing it. These compounds can prevent hemolysis of blood in contact therewith because of their erythrocytes-protecting activity.
A fuel composition comprising a major proportion by weight of a liquid hydrocarbon fuel and a minor proportion by weight of a polymer containing more than one amino group, this amino group being a salt of a primary, secondary or tertiary amine or a quaternary ammonium salt, for example an amine salt of a copolymer of an alkyl fumarate, vinyl acetate and maleic anhydride.
