The analysis of the best part for the strategy of molecular design for polymer flow improver by comparing two polymer additives, PEB and MAC, were illustrated. Model waxy oils were prepared by dissolving long chain n-parrafins octacosane (C28), dotriacontane (C32), and hexatriacontane (C36) in decane. Yield stress measurements were performed on a Rheometrics DSR controlled stress rheometer with parallel plate geometry. The results show that PEB-10 is more effective to decrease yield stresses of model waxy oils while MAC18-18 is more suitable for crude oils especially those containing asphaltenes.
