The amidation grafted copolymers derived from styrene-maleic anhydride copolymer were prepared and characterized by FTIR. Their intrinsic viscosity and crystal morphology were measured. The prepared polymers were investigated as pour point depressants (PPD) and flow improvers for waxy crude oil, and it was found that the depression effect of PPD modified by mixture amines was more effective than single amine, and the maximum depression was obtained by the sample that modified by mixture amines from 13 °C to 4 °C (ΔPP = 9 °C, at 3 000 ppm). The effect of the PPD modified by mixture amines on the flow properties of waxy crude oil was investigated. The result show that the viscosity decreased from 1 223 mPa.s to 81.3 mPa.s at 13 °C and 3 000 ppm. In addition, the crystal morphology have also been improved for the same sample and conditions.
