摘要: 本文合成了一种双官能度的氨基甲酸酯乙烯基醚和一种三官能度的氨基甲酸酯乙烯基醚,并用实时傅立叶红外光谱分别监测了单官能度、双官能度和三官能度的乙烯基醚化合物在三芳基六氟锑酸锍鎓盐阳离子光引发剂(PAG-201)引发下的光聚合情况,对其光聚合动力学性能进行了比较,研究了引发剂PAG-201的浓度对双官能度单体光聚合的影响.结果表明,随着官能度的增加,乙烯基醚化合物的转化率和聚合速率降低.此外,对它们的聚合产物进行的热失重分析表明,随着官能度的增加,聚合产物的热稳定性增加.本文的结果对于研究开发基于氨基甲酸酯乙烯基醚单体的阳离子聚合体系具有较好的指导意义.

Abstract: A difunctional vinyl ether and a trifunctional vinyl ether bearing carbamate-based monomers were synthesized and characterized. In this paper, the mono-, di- and tri-functional monomers were successfully polymerized by UV irradiation in the presence of photo initiator, mixed type triarylsulfonium hexafluoro antimonate salts (PAG-201). The polymerizing process was monitored by real-time infrared spectroscopy and the photopolymerization kinetics of the three monomers was compared. The influence of the concentrations of PAG-201 on photopolymerization of difunctional vinyl ether was also investigated. The results showed the double bond conversion and the rate of polymerization would decrease with the increase of the functionality, meanwhile, the thermo-stability of their polymerized products were improved with the increase of the functionality revealed by DSC. The above results were instructive to the research and development of cationic polymerization system of vinyl ether bearing carbamate-based monomers.

Key words: carbamate vinyl ether, cationic photo polymerization, polymerizing dynamics, thermal stability
