Departure from the vogel behaviour in the glass transition region-thermally sti...
Alves, N. M.; Mano, J. F.; Gómez Ribelles, J. L.; Gómez Tejedor, J. A.In this work the study of the dynamics of the segmental motions close to Tg of a poly(methyl methacrylate), PMMA, network was analysed by distinct mechanical spectroscopy techniques. Three techniques were employed: dynamic mechanical analysis (DMA), creep and thermally stimulated recovery (TSR). The time–temperature superposition principle was applied to the DMA and creep results, and master curves were success...
Viscoelastic behaviour of polymethyl methacrylate networks with different cross...
Alves, N. M.; Gómez Ribelles, J. L.; Gómez Tejedor, J. A.; Mano, J. F.The influence of the cross-linking degree on the dynamics of the segmental motions close to the glass transition of poly(methyl methacrylate), PMMA, networks was investigated by three different mechanical spectroscopy techniques: thermally stimulated recovery (TSR), dynamic mechanical analysis (DMA), and creep. The application of the time-temperature superposition principle to isothermal DMA and creep results p...
