The complex dynamic surface elasticity of the solutions of copolymer of sodium 2-acrylamido-2-methyl-1-propansulfonate with N-isopropylacrylamide and dodecyltrimethylammonium bromide was measured as a function of the surfactant concentration and the surface age by the oscillating bubble and drop methods. The kinetic dependencies of the surface elasticity proved to be non-monotonic at low concentrations and the main features of the surface viscoelasticity differed from the results for other polyelectrolyte/surfactant solutions films studied so far. The observed peculiarities were connected with the properties of the copolymer chain.
采用振荡气泡法和振荡液滴法，测量了2-丙烯酰胺基-2-甲基丙磺酸钠与N-异丙基丙烯酰胺和十二烷基三甲基溴化铵共聚物溶液的复杂动态表面弹性，该弹性是表面活性剂浓度和表面老化时间的函数。结果表明，在低浓度下表面弹性的动力学依赖性是非单调的，并且表面粘弹性的主要特征与迄今为止研究的其他聚电解质/表面活性剂溶液膜的结果不同。观察到的这些特性与共聚物链的性质有关。
