Abstract
New cross-linked poly(vinylalcohol) (PVA) hydrogel was obtained by the co-p olymerization of vinyl acetate and triallyl isocyanurate, followed by the a lkali-saponification. This PVA hydrogel possessed the same characteristics as a non-ionic 2-hydroxyethyl methacrylate (HEMA) hydrogel, the best shape stability for the salt-density and some changes of size for the temperature variations. And the higher cross-linked PVA hydrogel showed the better sta bility for the temperature variations. These results suggest that this cros s-linked PVA hydrogel will be promising as a biomedical nan-ionic hydrogel, particularly for ophthalmic applications.
