Hydration structures of a biocompatible polymer, poly(2-methoxyethyl acrylate) (PMEA), were investigated by in-situ ATR-IR spectroscopy. Time-resolved in-situ ATR-IR spectra of water sorption process into a PMEA film from dried condition to saturated hydration were monitored. Difference spectra, i.e., subtraction spectra at each time step A(tn) - A(t n-1), revealed that the band around 3600 cm-1 assigned to non-freezing water initially arises, followed by that around 3400 cm -1 of freezing bound water, and finally the band around 3200 cm -1 corresponds to freezing water increases. Hydration structures of each water in PMEA will be discussed in detail.
