摘　　要：合成了一种碱溶性三元无规共聚物甲基丙烯酸甲酯丙烯酸乙酯甲基丙烯酸(P(MMA/EA/MAA)),研究了浓度、十二烷硫醇(DDM)用量、pH值和甲基丙烯酸的用量对其表面活性的影响。结果表明,随着碱溶性无规共聚物的浓度和聚合过程中十二烷硫醇用量的增加,溶液的表面张力降低;当聚合过程中甲基丙烯酸的质量分数为25%或pH值为75时,所制得的碱溶性无规共聚物的溶液表面张力最低。An alkali soluble terpolymer P(MMA/EA/MAA) was synthesized. The effect of terpolymer concentration , amount of MAA and dodecylmercaptan(DDM) and pH on the surface activity of the terpolymer solution were investigated. The results showed that the surface tension of the polymer solution decreased with increase in terpolymer concentration and the amount of DDM. The polymer solution showed a minimum surface tension value when the mass fraction of MAA was 25% or the pH of the solution was 7 5.
