Table 1 shows the experimental conditions for the synthesis of azocellulose polymers through alkyl aryl ether formation via Mitsunobu reaction (Scheme 1). Samples AZOEST21 and AZOEST49 were prepared from ESTERCELL cellulose, and Sample AZOVIS69 was prepared from VISCOCELL cellulose. The degrees of substitution (DS) for these samples are 0.21, 0.49 and 0.69, respectively.
