Динамическая поверхностная вязкоупругость растворов поли(К-изопропилакриламида

The dynamic surface elasticity of aqueous poly(N-isopropylacrylamide) solutions has been measured as a function of time and concentration. While the real and imaginary parts of the surface elasticity almost did not change with the concentration, their kinetic dependencies proved to be non-monotonous. The results has been explained by the theory of dilational surface properties of non-ionic polymer solutions.
