Abstract
The states of water in PMEA and PHEMA were studied by using solid-state 2H-NMR. In order to investigate the behavior of water in PMEA, PHEMA, and their coploymeres, the temperature dependence (from -60 °C to 37°C) of 2H-NMR spectra and relaxation times were observed for the polymers with various contents of water. From the results of T1 the followings are concluded. The mobility of water molecule is high and hardly influenced by the water content in PMEA, while it depends strongly on the water content in PHEMA. In the range under 20% of the water content, the water in PHEMA is strongly bounded to the polymer.
