20. The formation of microphase separation cannot be excluded on the basis of the present data. However, it should be noted that these polymers are compatible to a large extent because the DSC curves of the blends exhibit no transition of the single component of the polymers for the blends and the IR spectra show the dominant formation of the phenol-pyridine complex.
