ABSTRACT: Novel polyurethane-imide elastomers were prepared
from isocyanates (hexamethylene, and 4,4’-dicyclohexyl
diisocyanates), polytetramethylene glycol (PTMG1000, Mw = 1000), pyromellitic dianhydride,
and 4,4’-diphenylmethane diamine. The formation of PUIEs was confirmed
by Fourier transform infrared spectroscopy. The resultant films were studied through
X-ray diffraction analysis, contact angle measurement, atomic force microscopy,
solubility and swelling tests, tensile test, differential scanning calorimetry,
dynamic mechanical analysis, and thermogravimetric analysis.
