摘要
针对高倾点石蜡基油品在低温环境下的储存、运输、装卸中存在的难题，合成了由丙烯腈和丙烯酸高级醇酯二元自由基共聚的倾点抑制剂PAAN，并对PAAN的聚合反应条件和过程进行了考察。n（丙烯酸）／n（丙烯腈）-3：1,-Mr=4．75×10^4，收率88N，产物降倾点效果较好，对其结构进行了表征，并初步探讨了其共晶-吸附作用机理。
Considering the difficulty of storage, transportation, loading and unloading for the distilled fuels with higher pour points, a pour point depressant, PAAN, was synthesized through radical polymerization of higher alkyl acrylate and acylonitrile. The reaction conditions were optimized and the functional mechanism of PAAN as a pour point depressant was discussed.
