| 摘 要： | 以N-甲基吡咯烷酮(NMP)作为助溶剂,偶氮二异丁腈(AIBN)作为引发剂,丙烯酰胺(AM)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)、丙烯酸十八酯(ODA)、苯乙烯(St)作为单体,通过无皂乳液聚合合成了阳离子高分子乳化剂(共聚物乳液),并制备了阳离子AKD/松香胶(施胶剂乳液)。考察了反应温度对单体转化率的影响及用不同w(AM)、w(DMC)、w(St)合成的共聚物乳液制备的施胶剂乳液离心稳定性能。结果表明:在共聚物乳液合成过程中,m(AM):m(DMC):m(St):m(ODA)=35:15:25:25时用其制备的施胶剂乳液具有较好的稳定性能;反应温度为70℃时单体转化率高,为95%。用最大气泡法测共聚物乳液的表面张力,得其临界胶束浓度为0.42×10-7mol/L。最后采用FT-IR对共聚物乳液进行了表征,纸张抄片结果表明施胶剂具有较好的防水性能。
