摘要
分别以十二烷基硫酸钠 (SDS)、壬基酚聚氧乙烯醚 (OP 10 )为表面活性剂 ,丙烯酰胺 (AM)的水溶液为连续相 ,苯乙烯 (St)为分散相 ,构成微乳液共聚合体系 ,合成了水溶性双亲嵌段共聚物 ,并通过荧光探针技术、差示扫描量热 (DSC)测试及流变性能的测定表征了共聚物的嵌段性结构 ,用红外光谱 (FTIR)及紫外光谱 (UV)
Block copolymerization of acrylamide(AM) and styrene(St) was carried out in a microemulsion system, in which AM aqueous solution was the continue phase and St was the dispersed phase using OP-10 and SDS as surfactants respectively. Water-soluble amphiphilic block copolymer of AM-St was synthesized. The block architecture of the copolymer was characterized by fluorescence probe technology and by measuring the DSC thermograms and the rheological property of the copolymer. The composition of the copolymer was analyzed by FTIR and UV methods.
