摘　　要：以甲基丙烯酸酯、马来酸酐和苯乙烯为原料,合成了甲基丙烯酸酯-马来酸酐-苯乙烯三元共聚物(MMS)柴油低温流动改进剂。通过对兰州石化公司的柴油的凝点和冷滤点测试,该剂可降低此混合柴油冷滤点4℃。用差示扫描量热法(DSC)探讨了柴油低温流动改进剂的作用机理。The synthesis of diesel fuel low temperature flow improver MMS and its effects on SP and CFPP depression for diesel fuel are introduced. The improver was produced by using methylacrylate,maleic anhydride and styrene as raw materials. This depressant was applied for the diesel fuels from Lanzhou Petrochemical Company; the CFPP（ Cold Filter Plugging Point） of the mix diesel fuels was lowered by 4℃. The phase transitions of diesel fuels with additive and diesel untreated during the cooling are researched by Differential Scanning Calorimetry（ DSC）.
