摘要(Abstract)：

为了制备结构可控的疏水疏油丙烯酸酯共聚物，以碘仿为链转移剂、偶氮二异丁基脒二盐酸盐（AIBA）为引发剂、十六烷基三甲基溴化铵/十六烷为主/助乳化剂，进行氟代丙烯酸酯-丙烯酸十八酯（FA-SA）碘转移细乳液共聚合。考察单体配比、聚合温度、引发剂浓度等对聚合动力学的影响，并对共聚物的结构和界面特性进行表征。结果表明：FA与SA质量比对初期聚合速率影响不大；聚合温度为60℃时，聚合速率较快，聚合转化率较高；随着AIBA浓度增大，聚合速率增大。碘仿调控的FA-SA细乳液共聚合可控性较好，符合一级动力学，具有活性自由基聚合特征。制备的FA-SA共聚物具有优异的疏水疏油特性，表面张力极低。
