摘　　要：研究评价了本课题组合成的低温流动性改进剂蜡晶分散剂M分别与乙烯 -醋酸乙烯酯共聚物、聚甲基丙烯酸高级酯之间的协同效应。结果表明 :M组分与乙烯 -醋酸乙烯酯共聚物复配使用时表现出了良好的协同效应 ,M和乙烯 -醋酸乙烯酯聚合物以及聚甲基丙烯酸高级酯组成的三元复配体系的协同效应更强 ,M具有助降冷滤作用。研究结果还表明 ,协同作用取决于M组分的分子结构 ,其中烃基链的长短具有重要影响。In this paper , the synergistic effects of 2 and/or 3 additive systems composed of M and ethylene-vinyl acetate copolymer and/or alkyl methacrylate polymer were studied It indicates that the 3 additive component system composed of M and ethylene-vinyl acetate copolymer and alkyl methacrylate polymer is more useful than 1 or 2 component systems in improving the cold flowability of distillate hydrocarbon fuel oils The alkyl length of M component is in connection with its ability for inhibiting agglomeration of the paraffin crystals and for dispersion of the crystals
