摘要：

The interactions between nonionic surfactants such as polyoxyethylene cetyl ethers (C16EO20) and the polymer gelatin were investigated by rheological methods. Capillary viscosity measurements of diluted aqueous solutions confirmed the results of previous investigations [1]. C16EO20 caused an accelerated renaturation of the polypeptide gelatin. A strong variation of viscoelastic data was measured by vibration rheometry when gelatin was added to the lyotropic cubic liquid crystalline phases formed by the surfactant used. Loss module (E'') and loss factor (tan phi) increased with increasing content of the polymer indicating an obstruction of the coupling between the globular surfactant associates.
