  • Solubility and diffusivity of CO2 in carboxylated polyesters
    Škerget, Mojca ...
    The solubility of CO2 in saturated polyester resins at different temperatures (306 and 343 K) and pressures (0.1-30 MPa) has been measured using a magnetic suspension balance. The solubility data ... were used for estimating the binary diffusion coefficients. The results show a good solubility of CO2 in polymers,up to 0.64 g CO2/g polymer. The diffusion coefficients of supercritical CO2 in polymers have generally high values and are in the range from 0.156 * 10-8 to 10.38 * 10-8 cm2/s. DSC and XRD analyses of the semi-crystalline polymer samples indicate that amorphous degree of polymers after exposure to CO2 is increased. The observed structural effects are dependent on pressure, temperature and time of exposure to CO2.
