The analysis of the substituent distribution over the chains of cellulose ethers is based on the determination of DS/DP profiles and the comparison of such profiles with the calculated random pattern. This analytical method requires that the polymer is degraded randomly and that the mass spectra of the oligosaccharide mixtures can be evaluated quantitatviely. While this approach is well established for methyl cellulose (MC), the application to other types of cellulose ethers is much more challenging. To find out whether depolymerization occurs in a random manner, kinetis of hydrolysis was studied for various cellulose ehers. Relative response of Electrospray Ionization (ESI) was also studied in dependence on chemistry and concentration of analytes. Results are presented and discussed.
