Rapid determination of γ-value and xanthate group distribution on viscose by liquid-state (1)H NMR spectroscopy

A method for the determination of the γ-value and more importantly the distribution of xanthate groups on cellulose xanthate produced during the viscose process is presented. The method is based upon stabilization of xanthate groups attached to the cellulose chain by reaction with 4-methylbenzyl bro...
