Abstract

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
