摘要：

Hyaluronic acid esters belong to a new class of polymers which have been developed in order to overcome water sensitivity displayed by hyaluronic acid. In this paper the effects of the substituting group on the water vapor transport properties were investigated. In particular, water sorption isotherms and kinetics for three types of hyaluronic acid esters (ethyl, dodecyl and benzyl esters) were determined. The type of substituent group has been found to affect polymer hydrophilicity and, consequently, the water swelling properties.
