Abstract:Developing cationic photopolymerizable fluorosilicone monomers is one of the
important research directions in the field of photopolymerization. A fluorosilicone glycidyl
ether epoxy monomer(FSi-GE)was synthesized by using readily available raw materials and
simple synthesis process,and the monomer structure was characterized using NMR and
FT-IR. The influence of FSi-GE on polymerization kinetics,surface water resistance,heat
resistance and tensile properties of the cationic photopolymerization system comprised of
3,4-epoxy-cyclohexyl methyl 3,4-epoxy-cyclohexyl formate(E4221)and 1,2-epoxy-4-
vinylcyclohexane(VOH)was investigated. The results showed that when FSi-GE amount was

elongation at break was increased from 22. 96% to 41. 22%,and the heat resistance was also
improved. However,with the further increase of FSi-GE amount,he surface water contact
