New polysaccharide esters are disclosed, and more precisely esters of acidic polysaccharides chosen from the group formed by carboxymethyl-cellulose, carboxymethyl starch and carboxymethylchitin. These new esters and some esters of the type already known are useful as medicaments, for the manufacture of pharmaceutical and cosmetic preparations, in the field of biodegradable plastic materials and, therefore, for the manufacture of medical, surgical and sanitary articles, as well as numerous other industrial sectors in the place of acidic polysaccharides now in common use. |
