Polymers of natural origin, including chitin and products of its degradation, attract attention of biomedical engineering specialists. The presented investigations of rheological properties of chitosan salt solutions are a basis for determination of initial parameters of chitosan membrane formation. They enable determination of homogeneity of the solution and polymer degradation degree in a given solvent.
