Synthesis and Properties of Novel Polyurethane-Imide Elastomers

Authors: Tomohiro Ueda, Shin-Ichi Inoue 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 … Continue reading
