Abstract

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).

某些三元共聚物作为润滑油添加剂的性能
在这项工作中,我们将丙烯酸与不同的醇(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。然后由苯胺与马来酸酐反应生成苯胺酰亚胺。以不同比例的苯胺、不同的烷基丙烯酸酯和烯烃为原料,通过聚合反应制备了不同的三元共聚物。用热重法测定了所制备的三元共聚物的热稳定性,表明其具有较高的热稳定性。聚合物在500°C以上被降解。聚合物(C)的流变行为表现为剪切减薄,接近理想的牛顿行为。制备的三聚体成功地将聚合物(C)的油粘度指数提高到118,将聚合物(E)的油倾点降低到-12。
