      摘要
    • 摘要: 以表面活性单体2-丙烯酰胺基十二烷磺酸钠(NaAMC12S)为表面活性剂构建了新的胶束共聚合体系,实施了丙烯酰胺(AM)与N,N-二正十二烷基丙烯酰胺(DiC12AM)的胶束共聚合,制备了含孪尾型丙烯酰胺的疏水缔合聚丙烯酰胺(HAPAM),该聚合物为三元共聚物DiC12AM/NaAMC12S/AM.通过控制共聚合条件,制得了微结构系列变化的共聚物;采用红外光谱法表征了三元共聚物的化学结构,用荧光探针法与表观粘度法重点研究了共聚物DiC12AM/NaAMC12S/AM的大分子链微结构与其疏水缔合性的关系.结果表明:新胶束共聚合体系大大简化了胶束的共聚合操作,而且由于表面活性单体进入共聚物主链,使三元共聚物DiC12AM/NaAMC12S/AM具有更强的疏水缔合性.与由单尾型丙烯酰胺N-正十二烷基丙烯酰胺(C12AM)为疏水单体制备的HAPAM相比,由DiC12AM制得的HAPAM疏水缔合性更为显著.
