2125402 9313137 PCTABS00024 A method for insolubilizing films of N-carboxyalkyl derivatives of chitosan uses an annealing process to provide materials which can have varied degradation times. These materials can be used for various biomedical applications such as adhesion prevention. The annealing process heats the film for predetermined times at predetermined temperatures to vary the solubility of the film.
