Supercritical CO2-assisted preparation of ibuprofen loaded PEG-PVP complexes

Author: Labuschagne, Philip W ; Kazarian, SG ; Sadiku, RE Date: Jun 2010 Stoichiometric ratios of poly (ethylene glycol) (PEG, Mw = 400) with poly(vinylpyrrolidone) (PVP, Mw = ±3.1 x 104 & Mw = 1.25 x 106 Mw) were prepared from ethanol cast solutions and in supercritical CO2. The complex formation was studied via ... Read more
