Abstract
Water absorbed in polyethylene terephthalate (PET) and sulfonated polyethylene terephtha-late copolymer (S-PET) were studied by FTIR spectroscopy. The FTIR spectra of PET and S-PET for different amounts of absorbed water were measured. The subtraction spectra of water containing PET have been determined using nitrogen dried PET as the reference. The characteristic bands arising from water-polymer interactions were obtained. The subtraction spectra show that four oxygen associated infrared bands 1720, 1260, 1122 and 1101 cm-1 were splitted into ten bands. The subtraction spectra of S-PET resemble those of PET. From observed results, a model of hydration in PET and its copolymer is suggested.
