Starch xanthates were first prepared over 50 years ago, and since then little has been learned about their chemical structure; even suggestions for their industrial utilization have been very few. In the meantime, the emergence of the viscose process and the rayon and cellulose film industries has stimulated a great amount of research on cellulose xanthates all over the world but, nevertheless, little knowledge has been gained about the distribution of the xanthate groups in the cellulose macro-molecule, and particularly within the anhydroglucose units. Only recently, attempts were made in these laboratories to locate the xanthate groups in samples of cellulose sodium xanthate.
