Comb-type poly(1-olefin-co-maleic acid alkylamine)s (MACs) with various lengths of side alkyl chain were synthesized. The effect of these copolymers on the cold flow ability of diesel was studied. The breaking point of diesel is defined as the temperature where the shear stress starts to show a sharp increase suddenly upon cooling. MACs can reduce the breaking points and improve the flow ability of diesel at low temperature as observed by rheology. The reduction on breaking point becomes more significant upon increasing the alkyl side chain length, as well as the dosage. MACs seem to be ideal cool diesel flow improvers.
