Time-resolved in-situ ATR-IR spectra of water sorption process into a biocompatible polymer, poly(2-methoxyethyl acrylate) (PMEA), were observed. Hydration structures of three different types of sorbed water in PMEA, i.e., non-freezing water, freezing bound water and freezing water, were discussed from the time-resolved IR spectra. ATR-IR spectra of water dissolved in a model monomer of 2-methoxyetyl acetate (MEAc) were also observed. ATR-IR spectrum of water in MEAc at 35 wt% shows similar spectra with that in PMEA at 9 wt% of saturated concentration. However, the mixture of water and MEAc (35 wt%) never shows cold crystallization peak in a DSC curve, implying that polymeric structure in PMEA may play an important role for the biocompatibility.
