摘要: 通过Ritter反应合成弱阴离子型疏水单体丙烯酰胺基十一烷基酸(C11AM). 以丙烯酰胺(AM)、甲基丙烯酰氧乙基三甲基氯化铵(DMC)和丙烯酰胺基十一烷基酸(C11AM)为原料, 在水介质中合成新型疏水缔合聚两性电解质AM/DMC/C11AM. 利用1H NMR确证了疏水单体和共聚产物的分子结构. 流变性和芘荧光探针的研究结果表明, AM/DMC/C11AM系列疏水缔合聚两性电解质由于兼具疏水缔合性质和反聚电解质效应, 使其具有较好的耐盐性能.

Abstract: A series of hydrophobically associating polyampholytes[poly(AM/DMC/C11AM)] was synthesized by the free radical polymerization in water. In this process, C11AM was synthesized by Ritter reaction, and used to copolymerize with acrylamide(AM) and [2-(methacryloyloxy)ethyl] trimethylammonium chloride. The structure of C11AM and poly(AM/DMC/C11AM) were confirmed by 1H NMR. Moreover, the rheology measurement and fluorescent characterization show that poly(AM/DMC/C11AM) possessed both of the hydrophobic association and antipolyelectrolyte behavior, which resulted in the super salt-resistance of the obtained polymers.
