- Аннотация: The swelling of poly(methyl methacrylate) and poly(butyl methacrylate) bulk samples in supercritical carbon dioxide was studied in situ. It was shown that the optical technique used to monitor the sorption process in the supercritical fluid allowed the diffusion coefficients of carbon dioxide molecules in the samples to be determined both by analyzing the movement of optical boundaries and from volume swelling kinetics. The diffusion coefficients in poly(methyl methacrylate) and poly(butyl methacrylate) were assumed to be concentration-dependent, and the models proposed were found to explain the formation of optical boundaries that had been detected experimentally in these samples. The experimental data were fitted to the results of computer simulation of the sorption process. Pore formation in the samples upon desorption of carbon dioxide in different exposure and decompression modes was visualized using optical (in situ) and atomic-force (ex situ) microscopy. The plasticizing effect of CO2 on the pore formation process is discussed.
