Temperature dependence of structural relaxation time in drawn polymers: Which is the role of cooperativity?. Hamonic, F., Saiter, A., Prevosto, D., Dargent, E., & Saiter, J. M. In AIP Conference Proceedings, volume 1459, pages 211–213, July, 2012. AIP Publishing.
Paper doi abstract bibtex The temperature dependence of structural relaxation time in drawn polyethylene terephthalate glycol and polyethylene terephthalate has been studied. A transition from fragile to strong behaviour is observed in drawn polyethylene terephthalate, which can be related to the decrease of Cooperative Rearranging Regions in such systems. The decrease is mainly due to the crystallization of the sample. Drawing the amorphous polyethylene terephthalate glycol poduces only small effects on its relaxation dynamics.
