In this paper, silicane modified copolymer hydrogel for contact lens with high oxygen permeability were prepared by copolymerization of KH570, N-Vinylpyrrolidone (NVP) and Hydroxyethylmethacrylate (HEMA) , influence of monomers on the properties of the hydrogel were studied, and delayed release of chloramphenicol by the hydrogel were studied as well.
When AIBN was used as initiator and the reaction carried on for 28 hours under the temperature of 80℃, the copolymer of KH570-NVP-HEMA was transpare...
