Keywords : experiments and modelling * polystyrene foams * CO2
Subject RIV: CI - Industrial Chemistry, Chemical Engineering

In our experiments, polystyrene films of the thickness of hundreds of micrometers up to a few milimeters were exposed to supercritical CO2 at saturation conditions in the range of 40-100 °C and 18-28 MPa. Additional experiments were conducted with polystyrene modified with light hydrocarbons. The cell size distribution and porosity of foams were measured and related to the saturation conditions and depressurization time.
