The effcct of thermal annealing on hydrogen bonding in 4,4'-diaminodiphenylmethane-bascd segmented polyurethanes (PUU) varying in the length of the poly(tctramcthylcne oxide) (PTMO)-bascd soft segments has been studied by using Fourier transformed infrared spectroscopy (FTIR). It has been found that a significant amount of both interurcthanc and hard - soft segment hydrogen bonding exists in the investigated PUUs. The later one indicates some degree of phase mixing leading to the hard segments being mixed into the soft domains. The spectral evidence for temperature effects on the hydrogen bonding have been demonstrated, which is based on the significant changes in the relative intensities of the bands corresponding to the free and different hydrogen- bonded C=0 groups as a result of the thermal treatment.
