GLYCERYL METHACRYLATE HYDROGELS

摘要

Hydrophilic three dimensional polymer networks (hydrogels) were prepared from glyceryl methacrylate (2,3-dihydroxypropyl methacry-late). The solubility of poly (glyceryl methacrylate) in water permits the preparation of transparent hydrogels containing variable amounts of water at the equilibrium stage;this is accomplished by varying the degree of swelling at the time of network formation, and by varying the density of cross-links. The temperature dependence of swelling of the hydrogels in water, and in 0.9% sodium chloride solution, was determined. There exists a linear relationship between the refractive index and the per cent of water in the hydrogel. These hydrogels are potentially useful in ophthalmology.
