摘　　要：用直接酯化法合成甲基丙烯酸高碳酯,再聚合生成聚甲基丙烯酸高碳酯类润滑油粘度指数改进剂。用甲基丙烯酸长链酯分别与马来酸酐、醋酸乙烯酯、甲基丙烯酸甲酯聚合生成二元聚合物,调合后考察不同单体对大石化生产的HVI150基础油粘度指数的影响,发现甲基丙烯酸长链酯与马来酸酐的二元共聚物有很好的效果,可以使粘度指数上升11。再加入第三单体与甲级丙烯酸长链酯、马来酸酐共聚,考察修饰后的效果。当加入其它类型的甲基丙烯酸长链酯时,也可得到较好的效果。选择效果好的剂,放大加剂量,也可获得比较理想的效果。The series of long-chained alky methylacrylates were synthesized by direct-esterification. The Viscosity Index Improver for lubricating oil was polymerized with long-chained alky methylacrylates synthesized above. The series of copolymer were synthesized with cetyl methylacrylate and Methyl methacrylate, malefic anhydride, vinyl acetate respectively. Through investigating 150SN, the result showed that one of coplymers comprising of cetyl methylacrylate and malefic anhydride has the best. Then polymerizing with a third monomer can produce adverse effects.
