摘要：

以α-甲基丙烯酸和马来酸酐为原料，经酯化反应合成了α-甲基丙烯酸高碳混合酯及马来酸酐高碳混合酯，确定了酯化反应条件。采用甲苯作溶剂，通过溶液聚合法合成了α-甲基丙烯酸高碳混合酯-马来酸酐高碳混合酯-乙酸乙烯酯-苯乙烯四元共聚物的柴油降凝剂，确定了最佳反应条件：单体配比1∶2∶3∶1，引发剂（偶氮二异丁腈）用量0.8%，反应温度为85 ℃，反应时间为6 h。考察了该降凝剂对锦州石化公司二套加氢柴油的降凝助滤效果，确定0.07%为降凝剂的最佳添加量。

Abstract:

α-Methylacrylic acid high-carbon mixed ester and maleic anhydride high-carbon mixed ester were synthesized from α-methacrylic acid and maleic anhydride respectively. The favorite esterification condition was determined. α-Methylacrylic acid high-carbon mixed ester-maleic anhydride high-carbon mixed ester-vinyl acetate-styrene tetra-polymer was prepared with toluene as a solvent via solution polymerization，the best reaction condition was obtained as：monomer ratio 1∶2∶3∶1，initiator（AIBN）0.8%，reaction temperature 85 ℃，reaction time 6 hrs. Its performance as a diesel pour point depressant is tested in the hydrogenated diesel fuels produced by Jinzhou Petrochemical Company unit No.2，the best addition dosage was 0.07%.
