Zusammenfassung:	PROBLEM TO BE SOLVED: To provide carboxylated cellulose ester derivatives with high acid numbers, wherein the carboxyl group is attached directly to the cellulose backbone by a carbon-carbon bond.SOLUTION: This invention relates to: cellulose ester interpolymers; and methods of oxidizing the cellulose ester interpolymers. Through functionalization of an intermediate aldehyde, the corresponding cationic or zwitterionic cellulose ester derivatives can also be used. The interpolymers have a number of end-use applications, for example, as binder resins in various types of coating compositions and as drug delivery agents.
