摘要：
Sorption properties of chitosan-based medicated films were studied. IR and UV spectroscopies were used to confirm that chitosan chemically interacts with medicinal preparations. It is assumed that structural changes occurring in the polymer matrix either as a result of introduction of medicinal substances, or in the course of isothermal annealing of films lead to significant departures of the fundamental aspects of the sorption process from the classical Fick's mechanism.
