Behaviour of amphiphilic polysaccharides in aqueous medium

Resumen

This paper describes the rheological and thermal behaviour of alkylated chitosan and hyaluronan derivatives and methylcellulose, Their behaviour is characterized by the formation of hydrophobic domains which may be considered as crosslinked points. Then, depending on the thermodynamic conditions (temperature, salt concentration), an aqueous solution transforms to a 3D-physical network  formed on the basis of  hydrophobic cooperative interactions.
