In this work, we prepared different alkyl acrylates by esterifying acrylic acid with different alcohols (decanol, dodecanol, hexadecanol and octadecanol). Anilimide was then produced by the reaction of aniline with maleic anhydride. Different teropolymers were prepared by polymerization reaction of anilimide, different alkyl acrylate esters and olefins in different ratios. The thermal stability of the prepared terpolymers was measured by thermal gravimetric analysis which demonstrated a high thermal stability. The polymers were degraded above 500 °C. The rheology behavior shows shear-thinning, it approaches the ideal Newtonian behavior in case of polymer (C). The prepared terpolymers succeeded in raising the viscosity index of oil to 118 in case of polymer (C) and decreasing the pour point of oil to -12 in case of polymer (E).

在这项工作中，我们通过丙烯酸与不同的醇（癸醇、十二醇、十六醇和十八醇）酯化制备了不同的丙烯酸烷基酯。然后苯胺与马来酸酐反应生成苯酰亚胺。以苯酰亚胺、不同丙烯酸烷基酯和烯烃按不同比例聚合反应制备了不同的三元共聚物。通过热重分析测量了所制备的三元共聚物的热稳定性，结果表明其具有高热稳定性。聚合物在 500 °C 以上就会降解。流变行为表现出剪切稀化，它接近聚合物 (C) 的理想牛顿行为。所制备的三元共聚物成功地将聚合物(C)的情况下的油的粘度指数提高到118，并且在聚合物(E)的情况下将油的倾点降低到-12。
