摘要

在使用各种结构的可逆链转移剂在自由基聚合条件下合成的甲基丙烯酸硬脂酯与马来酸酐的共聚物中,使用了聚合物类似转化法对共聚物进行改性。结果表明,甲基丙烯酸硬脂酯与马来酸酐的共聚物经 25% 的辛醇-1 改性后,在倾点为负 19°С时具有很高的减压效果,同时还能显著降低柴油的浊点值和最高过滤温度。因此,所获得的改性共聚物在实际用作燃料添加剂方面可能会很有意义。

Synthesis and modification of copolymers of stearyl methacrylate and maleic anhydride and study of their effect on low-temperature characteristics of diesel fuel
Polymer-analogous transformations have been used to modify copolymers of stearyl methacrylate with maleic anhydride synthesized under radical polymerization conditions using reversible chain transfer agents of various structures. It has been established that copolymer of stearyl methacrylate with maleic anhydride modified by 25% with octanol-1 has a high depressant effect for a pour point of minus 19°С and at the same time significantly reduces both the cloud point values and the maximum filterability temperature of diesel fuel. In this regard, the obtained modified copolymers may be of interest in terms of their practical use as fuel additives.
