Abstract
AbstractFour kinds of (cellulose oligo‐oxymethylene ether) acylates from the acetate to the valerate were prepared by homogeneous reactions using a DMSO/PF cellulose solvent as the reaction medium. The temperature variations of dynamic modulus, loss modulus, and loss tangent for these polymers were measured. Three types of relaxation process were observed for all (cellulose oligo‐oxymethylene ether) acylates, and an additional relaxation process was detected for (cellulose oligo‐oxymethylene ether) butyrate and valerate. These processes were labelled α, β, γ, and δ in order of decreasing temperature at which they occurred. These α to δ processes were respectively attributed to: micro‐Brownian motion (α), motion of side chains (β), local mode motion involving oxymethylene groups (γ), and motion initiated by three or more methylene groups (δ).
