Claim 8:
9. A method comprising:
adding a flow improver composition to a first hydrocarbon fluid to produce a second hydrocarbon fluid, the flow improver composition comprising a solvent; and a dendrimer-based flow improver that is a reaction product of a base dendrimer represented by the structure:, , and erucic acid or behenic acid,
wherein the base dendrimer comprises surface sites and at least 50% of the surface sites are chemically modified with erucic acid or behenic acid,
wherein at least one surface site is chemically modified via amidation with erucic acid and at least one surface site is chemically modified via amidation with behenic acid, and
wherein a mole ratio of erucic acid to behenic acid that undergoes amidation on the surface sites of the dendrimer is between about 10:1 to 1:10.
