dc.description.abstractEnAn FTIR (Fourier Transform InfraRed) microscope combined to a high pressure cell has been used to determine the CO2 uptake in several common elastomers. Both the CO2 sorption and the resulting swelling of the elastomers have been determined as function of pressure (P = 5–15 MPa) at constant temperature (T = 50 °C). A significant quantity of CO2 is sorbed in all studied elastomers, between 15 and 20% at T = 50 °C and P = 15 MPa for most elastomers and up to 30% for Ethylene Vinylacetate (EVM) in the same conditions. The resulting percentage of swelling of the majority of studied elastomers is significant (up to 30%), and varies quite proportionally with the CO2 mass uptake (linear variation with a slope equal to 1). The effect of temperature has been studied for Ethylene Propylene Diene (EPDM), between T = 50 °C and T = 110 °C (P = 5–15 MPa) and demonstrate that the swelling and CO2 sorption display only a weak variation in this temperature range.
