It was found that for COA with acyl chain with length short as the acetate group, the change in the length of the oxymethylene chain caused remarkable difference in their viscoelastic properties, while for COA with such long acyl chain as the decanoate group it induced little difference. Furthermore, the difference in viscoelastic properties between COA and the corresponding cellulose acylate also became negligibly small when their acyl chain was long enough as the decanoate group. In the process of these consideration, the β and γ processes for COA were respectively assigned to be due to the micro-Brownian motion along the side chain, and the motion of the oxymethylene groups in the side chain.
