| Abstract |
The main components of the polymerized hydrogel lenses at room temperature are 2-hydroxyethyl methacrylate (HEMA), distilled water and surfactants. Ethylene glycol dimethacrylate (EGDMA) was used as a lenses crosslinking agent differently depending on the kind of the sample. And also ammonium persulfate (APS) as an initiator was added to about 0.3%(wt). As a catalyst, about 2%(wt) of N,N,N’,N’-tertamethylethylenediamine (TMEDA) was used.
The hydrogel polymer was manufactured by using room temperature polymerization process and the measurement results of physical properties showed that contact angle of sample was in the range of 71.47~44.82°. The wettability was higher than that of heat treatment. Also the light transmittance was 90.24~94.28% for the visible light region, 68.63~85.79% for the UV-B region and 86.88~92.24% for the UV-A region respectively.
The produced copolymer by room temperature polymerization was suitable for hydrogel ophthalmic lens.
