Solute Diffusion into Polymer Swollen by Supercritical CO<sub>2</sub> by High-Pressure Electron Paramagnetic Resonance Spectroscopy and Chromatography

High-pressure electron paramagnetic resonance (EPR) was used to measure translational diffusion coefficients (D<sub>tr</sub>) of a TEMPONE spin probe in poly(D,L-lactide) (PDLLA) and swollen in supercritical CO<sub>2</sub>. D<sub>tr</sub> was measured on two scale...
