Abstract
Samples of carboxymethyl chitosan have been synthesized with different extents of substitution by changing the reaction conditions. Carboxymethyl chitosan completely dissolves in water when the extent of substitution exceeds 90%. The theological properties were studied for 4% aqueous solutions of carboxymethyl chitosan with CaCl2 and Ca(OH)2 as additives as well as for a mixture of carboxymethyl chitosan and polyethylene oxide with added CaCl2. The introduction of additives to aqueous solutions of carboxymethyl chitosan leads to enhanced viscosity and gel formation.
