Phase studies of a urethane model compound and polyether macroglycols by infrared spectroscopy and the relationship between eutectic composition of soft segment and blood compatibility.


The binary mixtures of a urethane model compound, diethyl 4,4'-methylenebis(N-phenylcarbamate) (MDU), and various polyether macroglycols have been investigated mainly by infrared (IR) spectroscopy. The mixtures of macroglycol and MDU showed two C=O bands (free C=O at higher wave number, hydrogen bonded C=O at lower wave number), and the intensity of free C… (More)
