新型杂化光聚合体系

光固化方式的复合化是对光固化体系进行改性的重要方法。通过将自由基和阳离子以及阳离子和阳离子配合组成新的光固化体系,可以得到优良的固化体系。本论文以多种丙烯酸酯,乙烯基醚,环氧树脂,以及实验室合成的杂化单体等做为基础材料进行混合杂化光聚合体系,杂化单体光聚合体系的光固化动力学比较,并对羟基化合物对各体系的影响进行分析。实验结果表明,杂化单体在转化率,转化速度,对羟基化合物不敏感性等多方面都比混合杂化体系有明显优势。

Photopolymer Zation of the New Hybrid System

Hybrid photopolymerization technique was an important method to optimise the photocuring system by overcoming the drawbacks and combining the merits of the separate photopolymerization systems.It might be consisted of free radical/cationic monomers or cationic/cationic monomers in one system.Hybrid systems or blend system formed by mixing acrylates,vinyl ethers,epoxy resins,and some hybrid monomers synthesized by our lab,respectively.The photopolymerization kinetics of these different hybrid systems was studied and the effect of hydroxyl compounds was performed as well.The results indicated that the mix-hybrid systems had rapid curing rate and high conversion and were easily influenced by environment.However,the effect of environment factors on photopolymerization of hybrid monomer system was decreased because of unique cuing mechanism of hybrid monomer system.
