摘要
以醋酸乙烯酯(VA)、苯乙烯(SE)、马来酸酯(ME)、α-甲基丙烯酸高碳醇酯(AE)作为单体,在一定条件下制得四元共聚物VSMA。该聚合物可以作为柴油低温流动性能改进剂,降低柴油的冷滤点和凝点。在添加量为0.05%时,可将吐哈0号柴油的冷滤点降低2℃,凝点降低7℃;可将吐哈-10号柴油的冷滤点降低4℃,凝点降低10℃。
A polymer VSMA, which could be used as diesel pour point depressants, was copolymerized withvinyl acetate, styrene, maleates and acylamide as material. It had good effect on improving the cold filter plugging point and solid point of several kind diesels. 0.05 % VSMA could decrease the cold filter point 2℃ andsolid point 7℃ of Tuha 0# diesel, cold filter point 4℃ and solid point 10℃ of Tuha - 10# diesel.
