Their hydrogen bonding and morphological structure were studied by means of Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and transmission electron microscopy (TEM). Compared with BDO-based polyurethanes, HQEE-based polyurethanes showed better phase segregation and higher extent of ordering in the hard domain. Besides short-range hydrogen bonds, a considerable amount of long-range hydrogen bonds existed in amorphous phase of the hard domain. The soft segment was easier to crystallize, and the melting temperature of the hard domain was elevated in HQEE-based polyurethanes. Its hard domain displayed a banded structure, rather than spherulitic structure in BDO-based polyurethanes. © 1999 John Wiley & Sons, Inc.
