The crystallization process of polyethylene oxide (PEO)/polymethyl methacrylate (PMMA) and PEO/polyvinyl acetate (PVA) blends has been characterized by Fourier Transform Infrared (FUR) spectra in conjuction with DSC. The crystallinity of PEO varies consistently with PEO content in PEO/PVA blends and the PEO/PMMA blends containing 50% or less PMMA. For the PEO/PMMA blends containing 60% or more PMMA
the crystallinity of PEO decreases more than PEO content but develops with crystallization time. These results can be explained in terms of difference between the crystallization temperature and Tg values of the blends as a function of content of non-crystalline component.
