A photooptical study on the kinetics of impregnation of selected polymers in a near-critical CO2
Impregnation of poly(methyl methacrylate) with pure supercrit. CO2 was followed in Authors' orig. app. via the optical front observed thanks to the impregnation-affected polymer's refractive index. This impregnation proceeded at a const. diffusion coeff. (Fickian release)
