Abstract
AbstractSummary: The hydrogen bonding and phase behaviour of blends of poly(vinylphenol‐co‐methylmethacrylate) (PVPhMMA50) containing 50% of methyl methacrylate with poly(vinylmethylketone) (PVMK) were investigated by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR). It was shown that all the blends have a single glass transition over the entire composition range. The FTIR study reveals the presence of intermolecular hydrogen‐bonding interactions occurring between hydroxyl and carbonyl groups of vinylphenol (PVPh) and (PVMK) and intensified when the amount of PVMK increased in blend. A new band characterizing these interactions at 1713 cm−1 was observed. Furthermore, the quantitative FTIR study carried out for PVPhMMA50/PVMK blends was also performed for the vinylphenol and vinylmethylketone functional groups.
