Abstract: This paper reports the results of the study on the influence factors and properties of the electron beam synthesis hydrogel material.
1 High quality hydrogel matericl can be obtained by the electron beam of high doge rate at the normal temperature.
2. In the range of l-10×l0Gy/s and l~2×l0Gy, the dose rate and the dose have no evident influence on the properties of soft contact lens.
3. When a moderate amount of water is added to the compounding, the elongation can be increased.
4. When the compounding includes the water-hating monomer such as butyl acrylate, the tensile strength of soft lens is increased and the water absorption is decreased.
5. The hydrogel material accords completely with the demands of biology.
