Investigation of the degree of homogeneity and hydrogen bonding in PEG/PVP blends prepared in supercritical CO2: Comparison with ethanol-cast blends and physical mixturesLabuschagne, PW, John, MJ, Sadiku, RE 04 February 2010 (has links)
Abstract
The degree of homogeneity and H-bond interaction in blends of low-molecular-mass poly(ethylene
glycols) (PEG, Mw = 400, 600, 1000) and poly(vinylpyrrolidone) (PVP, Mw =9×103) prepared in supercritical
CO2, ethanol and as physical mixtures were studied by differential scanning calorimetry (DSC),
Fourier-transform infrared (FTIR) spectroscopy and dynamic mechanical analysis (DMA) techniques.
Homogeneity of samples prepared in supercritical CO2 were greater than physically mixed samples,
but slightly less than ethanol-cast samples. PEG–PVP H-bond interaction was higher for ethanol-cast
blends when compared to blends prepared in supercritical CO2. This reduced interaction was attributed
to a combination of: (1) shielding of PEG–PVP H-bond interactions when CO2 is dissolved in the blend;
(2) rapidly reduced PEG and PVP chain mobility upon CO2 venting, delaying rearrangement for optimum
PEG–PVP H-bond interaction.
