Poly(1-olefin-co-maleic anhydride amide)s (MAC) with different side-chain lengths were synthesized. They could improve the flow ability of cold crude oils significantly. The yield stress results showed that MAC is especially effective for crude oils containing asphaltenes because of the interaction between carboxyl groups in MAC with polar groups in asphaltenes. Moreover, MAC could reduce the crystals size, depress crystallization temperature, and decrease crystal amount when cooling crude oils. The effectiveness of MAC for oil flow improvement was also related to side alkyl chain length. MAC with longer side-chain showed better results. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
