For the first time, impregnation of thermoresponsive graft copolymer between N-isopropylacrylamide and oligolactide (P(NIPAM-co-PLA)) with stable nitroxyl radical 4-oxo-2,2,6,6-tetramethyl-piperidine-1-oxyl (TEMPONE) was performed in SC-CO2 medium using a high-pressure reactor, which allows registering electron paramagnetic resonance (EPR) spectra in situ.
