Influence de la température sur les réactions viscoélastiques de vulcanisats de caoutchouc susceptibles de cristalliser au cours d’essais de traction monoaxiale

Ageing of natural rubber under stress

“…In classical studies of rubber relaxation, e.g. of Ferry [11] and of Chasset and Thirion [12], the time scale of experiments was usually under 10 5 s -rather like our 'relatively short time regime' in Figure 4. Authors reported power-law dependencies of stress, σ ∼ (t/τ ) −m , which has been attributed to the effect of retracting of freely dangling chains on network deformation [13].…”

Viscoelastic properties of cross-linked solutions of poly(β-hydroxyethyl methacrylate) in diethylene glycol

“…:For samples 1 and 2 of fig. 1, the curvature permitted use of the Thirion equation (9,14) for the estimation of log Je. However, in this case the calculated values were slightly higher because the additional creep effect was included here already from short times of the experiment.…”
