摘要
从丙烯酸Ｃ１６－Ｃ１８醇酯制备开始，在室内合成了丙烯酸混合酯－马来酸酐－醋酸乙烯酯三元共聚物ＣＯＶＡＭ。
The synthesis of terpolymer of mixed ester of acrylic acid and C16-C18 mixed alcohol,maleic anhydride and vinylacetate,COVAM,starting from C16-C18 alcohol is presented breafly.The pour point depression by COVAM is investigated for Shengli-Zhongyuan(S-Z) mixed crude in some detail and for Shandong-Nanjing pipeline crude and North Jiangsu crude tantatively.For S-Z crude,0.10% COVAM reduces pour point from 30℃ to 18℃ and apparent viscosity at 30-50℃ by 17% -61% and yield stress at 30℃ and 35℃ by 77%-79% at shear rate 49.81ls(-1).
