Poly(1-olefin-co-maleic anhydride amide)s (MAC) with different side-chain lengths were synthesized. They can improve the cold flow ability of crude oils significantly, The yield stress results show that MAC is especially effective to improve cold flow ability for crude oils containing asphaltenes because of the interaction between carboxyl groups in MAC with polar groups in asphaltenes. MAC can reduce the crystal size, depress crystallization temperature, and decrease crystal amount when cooling crude oils. The effectiveness of MAC for oil flow improvement is also related to side alkyl chain length.
