Resum
The viscoelastic response of some vinylic copolymers of cellulose prepared with vinyl acetatemethyl acrylate mixtures and with Ce(IV) ion as initiator, and native cellulose, were studied at 110 Hz in a range of temperatures from -120–100°C. The viscoelastic spectrum of cellulose shows the ß-relaxation that is not shown in its vinylic copolymers. We observed the same effect in the dielectric-relaxation. For the vinylic copolymers of cellulose, one viscoelastic relaxation attributed to the a-r...
