摘要:: 以非离子表面活性剂失水山梨醇单油酸酯(Span80)和聚氧乙烯失水山梨醇单油酸酯(Tween80)为复配乳化剂,环己烷为油相,以NaHSO3和(NH4)2S2O8为氧化还原引发剂,进行了丙烯酰胺(AM)/对苯乙烯磺酸钠(SSS)的反相微乳液聚合,研究了亲水-亲油平衡值(HLB)、油水比、乳化剂用量、温度和单体AM/SSS的比例对反相微乳液稳定性的影响.得出了反相微乳液的优化配方,并以该配方进行了反相微乳液聚合,得到了分子量为4×106的聚合物.聚合物的红外特征图谱表明,聚合物分子上有酰胺基和苯环、磺酸根存在.

Abstract:: The inverse mieroemulsion copolymerization of acrylamide and sodium styrene sulphonate was investigated，when cyelohexane oil phase，acrylamide(AM)and sodium styrene sulphonate(SSS)monomers，nonionic surfactants Span80 and Tween80 emulsifier，NaHS03 and(NH4)2S2 08 redox initiator were used．Effects of hydrophilie—lipophilie balance(HLB)value，mass fraction of oil／water，temperature，the dosageof emulsifier concentration of monomer aqueous solution，the proportion of AM／SSS on the stability of inversemicroemulsion are studied．The best polymerization condition was obtained．Under the optimized conditions，the molecular weight of polymer is 4×1 06 and FTIR proved the existence of amide carbonyl．benzene and sul—fonic group in the polymer．
