    • Le vieillissement thermo-oxydant des polymères est-il modélisable ? 
      Article dans une revue avec comité de lecture
      AUDOUIN, Ludmila; VERDU, Jacques; ccFAYOLLE, Bruno; ccCOLIN, Xavier; ccRICHAUD, Emmanuel (EDP Sciences, 2010)
      It has been supposed, for a long time, that kinetic modelling of polymer ageing for nonempirical lifetime prediction was out of reach for two main reasons: hypercomplexity of mechanisms and heterogeneity of reactions. The ...
    • Kinetics of chlorine-induced polyethylene degradation in water pipes 
      Article dans une revue avec comité de lecture
      DEVILLIERS, Clémence; LAIARINANDRASANA, Lucien; OBERTI, Sandrine; GAUDICHET-MAURIN, Emmanuelle; ccFAYOLLE, Bruno (Elsevier, 2011)
      The presence of chlorine in drinking water supplies in many countries creates the undesirable side effect of causing a relatively under investigated degree of polymer degradation in the polyethylene pipes used for transport. ...
    • Barrier properties of poly(lactic acid) and its morphological changes induced by aroma compound sorption 
      Article dans une revue avec comité de lecture
      COLOMINES, Gael; DUCRUET, Violette; COURGNEAU, Cécile; GUINAULT, Alain; DOMENEK, Sandra (Wiley, 2010)
      The barrier properties of poly(lactic acid) (PLA) play a key role in food packaging applications. For their optimization, the influence of crystallinity on the barrier properties of PLA and the interaction of PLA with the ...
    • Analysis of the Structure-Properties Relationships of Different Multiphase Systems Based on Plasticized Poly(Lactic Acid) 
      Article dans une revue avec comité de lecture
      COURGNEAU, Cécile; DOMENEK, Sandra; GUINAULT, Alain; AVÉROUS, Luc; DUCRUET, Violette J. (Springer Verlag, 2011)
      Poly(lactic acid) is one of the most promising biobased and biodegradable polymers for food packaging, an application which requires good mechanical and barrier properties. In order to improve the mechanical properties, ...
    • A kinetic model for predicting PET macromolecular changes during its mechanical recycling 
      Article dans une revue avec comité de lecture
      NAÏT-ALI, Linda K.; BERGERET, Anne; ccCOLIN, Xavier (EDP Sciences, 2011)
      The rheometer cavity has been used to analyse, in carefully controlled exposure conditions, the macromolecular changes generated by the mechanical recycling of PET during its extrusion. Isothermal ageing tests at 280 °C, ...
    • Kinetic analysis and modelling of PET macromolecular changes during its mechanical recycling by extrusion 
      Article dans une revue avec comité de lecture
      NAÏT-ALI, Linda K.; BERGERET, Anne; ccCOLIN, Xavier (Elsevier, 2011)
      The rheometer cavity has been chosen to analyze, in carefully controlled exposure conditions, the PET macromolecular changes generated during its mechanical recycling by extrusion. Isothermal ageing experiments at 280 °C, ...
    • Ring tests on high density polyethylene: Full investigation assisted by finite element modeling 
      Article dans une revue avec comité de lecture
      LAIARINANDRASANA, Lucien; DEVILLIERS, Clémence; OBERTI, Sandrine.; GAUDICHET, E; LUCATELLI, Jean Marc; ccFAYOLLE, Bruno (Elsevier, 2011)
      In order to characterize the mechanical behavior of HDPE pipes, the ASTM D 2290-04 standard recommends carrying out tensile tests on notched rings, cut out from the pipe. This very simple test is also utilized to investigate ...
