Abstract
Using IR spectroscopy, elemental analysis, and potentiometric titration, it was confirmed that amidation and cross linking of the polymer take place in heat treatment of chitosan films in the S-form. It is shown that these processes also take place in hardening of films from formic acid solutions of chitosan by vaporization of the solvent at high temperature.
