摘　　要：以甲基丙烯酸十四酯-马来酸二异辛酯-苯乙烯三元共聚物降凝剂为主剂,分别与表面活性剂和极性化合物进行复配,研究了不同配比下复配物的降凝效果。结果表明:在相同质量比的情况下,降凝剂与表面活性剂复配后的降凝效果优于与极性含氮化合物复配后的降凝效果,其中,降凝剂与司盘40的复配物降凝效果最好,当复配质量比为4∶1时,可使150SN基础油凝点降低26℃。In the experiment,the depressant of tetradecyl methacrylate-diisooctyl maleate-styrene polymer was used as main agent of compound,and the surfactant or polar substance was used as assistant.The pour point depressing performance of the compound was studied and the results showed that the effect of surfactant was better than polar substance and when the ratio of depressant and span 40 was 4 ∶1,the effect was best and the solidifying point of the150 SN base oil decreased 26 ℃.
