| Abstract |
This study was planned considering the two types of silicone monomers and DMA ratio to be used in the polymerization. For the preparation of silicone hydrogel lens materials, based of TRIS[3-(methacryloyloxy)propyltris(trimethylsiloxy)silane] in the presence of SiD-2, DMA(n,n-dimethylacrylamide) was used as additive. The measurements of the water content, showed a different water content value for each lens with silicone monomers. The physical properties of the produced polymer with addition of SiD-2 showed that the water content increased as the ratio of additive increased. Also, the polymer including TRIS, the average value of water content decreased as the ratio of additive increased. And also, the Dk measurement of the samples containing SiD-2 and TRIS showed that the average value was in the range of 26.75~32.36×10-11(cm2/sec)(mlO2/ml×mmHg). Silicone monomers containing DMA was expected to be used usefully as a material for high oxygen permeability and high water content silicon hydrogel ophthalmic lens. |
