Swelling and Plasticization in Glassy Polymer/Gas-Systems - Combined Examination of Experimental and Modelling Results — •Ole Hoelck1, Martin Boehning1, Martin Siegert2, and Matthias Heuchel21Bundesanstalt fuer Materialforschung und -pruefung (BAM VI.3), Unter den Eichen 87, 12200 Berlin — 2GKSS Forschungszentrum Geesthacht GmbH, Inst. f.

Swelling and plasticization of glassy polymers upon sorption of gas molecules affects several application relevant properties as well as the general stability and reliability of the polymer matrix. This joint research project of experimental evaluation and molecular modelling aims at the convergence of boundary conditions of both, experiment and simulation, to enable a comparison and complementary analysis of their results, in order to gain a deeper understanding of the phenomena on the molecular level. Presented results - focussed on the polysulfone/carbondioxide-system - concerning corresponding changes in physical properties of simulation and experiment are subjected to interpretation in terms of the site-distribution model as well as other phenomenological gas transport models.
