- ... The 4-amino-2,2,6,6-tetramethylpiperidine-1-oxy radical (4-amino-TEMPO)-mediated oxidation was applied to regenerated cellulose, and the obtained cellouronic acid was analyzed by size-exclusion chromatography attached with a multi-angle laser light scattering detector (SEC-MALS). Although the cellouronic acid filtered with the usual 0.1 μm membrane gave a bimodal SEC-elution pattern, the high-mole ...
