Abstract
The extent of hydrogen bonding between urethane and urea hard segments and polyether soft segments was studied using differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy. Model urethane and urea compounds were prepared and characterized. These models were then blended with polyether oligomers at different ratios. The change in melting peaks in both positions and enthalpies were used to measure the extent of hydrogen bonding in these systems. The DSC scans were compared with FTIR observation and also with quantum mechanical calculations.
