摘　　要：以甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)和甲基丙烯酸(MAA)为单体,利用溶液聚合法,以异丙醇为溶剂,偶氮二异丁腈为引发剂,在85℃的条件下合成一种水溶性三元共聚破乳剂。考察了各单体及引发剂用量对合成破乳剂脱水率的影响。实验表明,各种单体及引发剂均存在最佳用量,即在单体质量比MMA∶BA∶MAA为4∶33∶7,单体总量44g,引发剂含量为1.0g的条件下,合成聚合物的破乳效果最好,在破乳剂浓度为300mg/L时,脱水率可达45%。The ternary co-polymerization has been synthesized through solution polymerization by using the dissolvent of isopropanol, the initiator of azodiisobutyronitrile and the monomers of methyl methacrylate(MMA), butyl acrylate(BA) and methacrylic acid(MAA) at 85℃. The paper respectively studied the effects of the monomers and initiator on the dehydrate rate of the demulsifier .The experiment results show the initiator and the monomers have optimum dosage and the effect of demulsify is high when the mass ratio of monomers (MMA:BA:MAA) is 4∶33∶7, the gross mass of monomers is 44g and the initiator is 1.0g. And when the concentration of demulsifier is 300mg/L, the dehydrate rate reaches 45%.
