摘要
以十二烷基硫酸钠(SDS)为表面活性剂,丙烯酰胺(AM)的水溶液为连续相,N,N-二丁基丙烯酰胺(DiC4AM)为分散相,采取先加碱共聚-共水解的方法合成了孪尾疏水缔合水溶性聚合物聚(丙烯酰胺/丙烯酸钠/N,N-二丁基丙烯酰胺)[P(AM/NaAA/DiC4AM)]。用FT IR1、H NMR对其结构、组成进行了表征和测定。用稀释外推粘度法测定了共聚物的特性粘数[η]、Huggins常数KH。用芘荧光探针法及表观粘度法研究了大分子链间的疏水缔合作用,考察了疏水单体用量对其水溶液表观粘度的影响。
A series of twin-tailed hydrophobically associating water-soluble terpolymers poly（acrylamide/sodium acrylate/ di-n-butylacrylamide） [P（AM/NaAA/DiC4AM）] were synthesized by the way of co-hydrolysis with alkali before micellar copolymerization. The structures and compositions of the terpolymers were characterized and determined using FT IR and H NMR spectroscopy. The intrinsic viscosities [ η] and Huggins constants KH were determined by dilution method using an Ubbelohde viscometer. Hydrophobically associating properties of the terpolymers were investigated by flurescence probe technology and viscosity behavior measurement. The influences of hydrophobe content and polymer concentration on apparent viscosity and critical associating concentration（CAC） were studied.
