Two native celluloses with different nanofibril widths and crystallinity were subjected to TEMPO‐mediated oxidation. Constant‐time heteronuclear multiple‐bond correlation analysis of the water‐soluble products and subsequent surface peeling revealed that more than 90 % of the products were (1→4)‐β‐linked glucose/glucuronic acid (Glc/GluA) alternating copolysaccharides (see scheme; TEMPO=2,2,6,6‐tetramethylpiperidin‐1‐yloxyl).
