Surface acetylation of bamboo cellulose: Preparation and rheological properties

► Purified bamboo cellulose was used to synthesize cellulose diacetate (B-CDA). ► B-CDA was dissolved in acetone/DMAc and the rheological properties were studied. ► The dependence of ηα, n, and Δη on concentration and temperature was analyzed. ► Eη was used to measure the dependence of solution viscosity on temperature. ► The results are favorable for predicting the B-CDA solution spinnability.
