Come-type copolymers (MACA) were prepared by grafting 2-aminobenzimidazole and octadecylamine on to poly(maleic anhydride –co–α-octadecene). Containing of heterocycle units, they were found to work better on reducing the yield stress of model oils and improving the flowability of crude oils than other maleic anhydride copolymers. MACA were able to reduce the size of wax crystal and to change the shape of crystal. The polar heterocycle groups have the similar structures with asphaltenes, which can impede the formation of asphltene aggregation. The fluorescent heterocycle group can help to observe the interactions between wax crystal and MACA copolymers under optical microscopy.
