Abstract

Highly biocompatible polymer, poly(2-methoxy acrylate) (PMEA) has unique hydration structures. Confirmed by DSC, there exist three kinds of sorbed water: non-freezing, freezing bound and freezing water. From the difference IR spectra of the broad OH stretching band, each hydration band was reasonably separated but had significant noise. By using multivariate analysis method, these noisy bands were optimized to be smoother, and the coefficient for each band was determined and provided very meaningful quantitative information. Also, the plot of these coefficients against time, shown in Figure 3, indicates the water sorption kinetics concerning each component. This result verifies the band assignment and clarifies the water-polymer molecular interaction.
