Abstract

Segmented polyester polyurethaneurea (PUU) based on 4,4'-disphenylmethane diisocyanate (MDI), ethylene diamine (ED) and polybutylene adipate (PBA) elastomers and their deuterated polymers were studied by means of IR spectroscopy. The results indicated that IR bands of hydrogen bonded N-H vibrations involved in PUU were greatly affected by deuteration. The bands which were sensitive to deuteration were those near 3,332, 3,190, 1,600, 1,539, 1,317, 1,257 and 1,230 cm-1, respectively. In addition, it was also found that PUU samples with different hard segment contents and polyester soft segment molecule weights were similarly affected by deuteration in degree.
