   Sammanfattning : The adsorption mechanism of 1-vinyl-2-pyrrolidone (VP), poly(1-vinyl-2- pyrrolidone) (PVP) and azelaic acid on synthetic gamma-aluminium oxide surfaces was investigated using FT-IR, FT-Raman, UV, 1H and 13C NMR spectroscopy. (Liquid-solid state) As a first step the solvation of VP and PVP in solvents of varying polarity, specifically water, ethylene glycol (EG), chloroform and carbon tetrachloride, was studied. LÄS MER
