Abstract

La presente invenzione concerne dei nuovi esteri carbossilici di un polisaccaride costituito da unità di acido 2-amino-2-deossi-glucuronico, e da glucosamina e dei loro N-acil derivati. Tale polisaccaride è un derivato del chitosano ottenuto per ossidazione di gruppi alcolici primari a gruppi carbossilici.
