Amphoteric and biodegradable polycarboxylates having a varying amount of unreacted glucosamine moieties as the biologically active group as well as the biodegradable moiety were prepared by the partial oxidation of chitosan using sodium periodate at pH 3.0 followed by oxidation with sodium chlorite. Partially dicarboxylated chitosan containing more than about 50% unreacted glucosamine residue showed good biodegradation using activated sludge for 28 days.
