The temperature calibration of the apparatus is discussed. Each thermal sampling experiment is analysed according to a simple Voigt\u2010Kelvin model in which the temperature dependence of the retardation time follows the Arrhenius equation with two adjustable thermokinetic parameters. Non\u2010linear fittings of the experimental data are performed with the corresponding constitutive equation. Both the activation energy and the pre\u2010exponential factor follow the usual trends with temperature and present the well\u2010known compensation phenomena. A divergence between the TSR results of the two materials is found above \u00b1 145\u00b0C and may be a result of the effect of the interface. The observed movements in the glassy state which are still found to have a cooperative character are analysed according to the Adam\u2010Gibbs theory. Dynamic\u2010mechanical relaxation properties of the composite are reported and analysed in terms of Takayanagi's block model.<\/jats:p>","DOI":"10.1002\/masy.19991480133","type":"journal-article","created":{"date-parts":[[2011,3,7]],"date-time":"2011-03-07T23:22:34Z","timestamp":1299540154000},"page":"437-454","source":"Crossref","is-referenced-by-count":13,"title":["Molecular motions in a polycarbonate composite as studied by thermally stimulated recovery and dynamic mechanical analysis"],"prefix":"10.1002","volume":"148","author":[{"given":"Nat\u00e1lia M.","family":"Alves","sequence":"first","affiliation":[]},{"given":"Jo\u00e3o F.","family":"Mano","sequence":"additional","affiliation":[]},{"given":"Jos\u00e9 L.
