摘　　要：以N乙烯基吡咯烷酮(NVP)、甲基丙烯酸羟乙酯(HEMA)以及γ(甲基丙烯酰氧)丙基三甲氧基硅烷(KH570)为原料单体,N,N’亚甲基双丙烯酰胺(NMBA)为交联剂,偶氮二异丁氰(AIBN)为引发剂,采用本体聚合法制备有机硅改性共聚物水凝胶接触镜材料,并研究了材料拉伸强度的影响因素。结果表明,所得材料的折光度为1.51,透光率达99%以上;有机硅的引入能显著提高材料的拉伸强度,NVP含量的增加使材料的拉伸强度下降。Hydrogel for contact lens was synthesized by copolymerization of NVP, HEMA and KH570,and the mechanical properties of the copolymer hydrogel was studied as well. The ~results showed that refraction degree of the hydrogel was 1.51, and its transparence was over 99%. KH570 could improve the material’s draw intensity notably, while the increase of NVP content ~decreased its draw intensity.
