The aim of the research was to test the advantages of spin probe electron paramagnetic resonance approach in studying polymers impregnation with organic molecules in supercritical CO2 (scCO2) The impregnation of bisphenol A polycarbonate with the spin probe TEMPOL was carried out at 307–343 K and 11.6–35 MPa. The mean and local concentrations of the spin probe in the polymer were evaluated. An increase...
