Abstract
罗丹明B荧光探针发现丙烯酰胺(AM)/丁基苯乙烯(BST) /2-甲基-2-丙烯酰胺基丙磺酸钠(NaAMPS)共聚物(PASA)在0.05 g/dL水溶液中疏水微区的黏度已较大,说明PASA具有强的疏水缔合效应.动态光散射结果表明,PASA在0.005 g/dL极稀溶液中,主要以单分子存在,部分单分子链发生了分子内缔合;在0.01 g/dL～0.2 g/dL范围内,溶液中均有构象伸展和卷曲的单分子存在,粒径有单分子区和疏水缔合区;当共聚物浓度增加为0.3 g/dL时,流体力学半径分布为单分散,只有缔合体存在.随着分子中疏水链段含量的增加,0.1 g/dL PASA溶液的疏水缔合体(Rh:2800 nm～5000 nm)的数量增加,溶液黏度显著升高.
