Rheological characteristics of aqueous solutions of mixtures of chitosan and polyoxyethylene

Summary

The rheological characteristics of aqueous solutions of chitosan and polyoxyethylene (POE) with molecular weight in the range of 105–106, as well as of their mixtures are described. It is found that the solutions of each polymer as well as of their mixtures exhibit pseudoplastic non-Newtonian behaviour which is described by the Ostwald-de-Waele model. It is proposed that the chitosan macromolecules determine the rheological behavior of the chitosan/POE mixtures.
