摘要

以环氧环己烷和甲基丙烯酸为原料，通过环氧开环反应，合成了邻羟基环己基甲基丙烯酸酯(HCMA)单体。采用实时红外光谱技术(RTIR)研究了单体结构、光照强度、不同引发剂及引发剂浓度对光聚合动力学的影响。合成的单体与甲基丙烯酸羟乙酯(HEMA)混合，采用光聚合方法制备水凝胶，通过动态力学热分析(DMA)测定对比了共聚水凝胶与均聚水凝胶的力学性能。结果表明，增大光强和引发剂浓度可提高体系双键转化率；含HCMA共聚单体的水凝胶的储能模量和损耗模量高于均聚水凝胶。

Abstract

A hydroxyl methacrylate monomer,o,-hydroxycyclohexyl methacrylate (HCMA), was synthesized by opening ring reaction of cyclohexene oxide with methacrylic acid. Real time infrared spectroscopy (RTIR) was used to study the effect of molecule structure, light intensity, various photo-initiator and initiator concentration on photo-polymerization kinetics. HCMA and HEMA as comonomers were utilized to prepare hydrogel by photo-polymerization method. The mechanical strength of poly (hydroxyethyl methacrylate) (HEMA) and poly (HEMA-co-HCMA) hydrogel was conducted by dynamic mechanical analysis (DMA). The results demonstrated that increasing of light intensity and photo-initiator concentration escalate final double bond conversion. And the storage module and loss module of poly (HEMA-co-HCMA) hydrogel were higher than those of poly (HEMA) hydrogel.
