Novel comb-type poly(a-olefin-co-maleic acid alkylamide)s from mixed a-olefinswith carbon number over 20 (MMAC) were synthesized. Rheology and polar light microscopy were adopted to assess the effect of copolymers on improvement of coal flow ability of model waxy oils containing 8% C24 (tetracosane) in decane. Upon addition of 0.5% MMAC, yield stress of model oil can be reduced by 69%, which showed better performance than MAC18 from a-olefin with a carbon number of 18. It confirmed that the lateral alkyl chain length of comb-type copolymer has strong impact on its performance to improve the coal flow ability of waxy crude oils.
