Abstract:

UV-curing of TMPTA and different ethoxylated TMPTA was studied respectively in air or nitrogen by UV-DSC.The oxygen inhibition in initial stage of curing was evaluated by the difference of the time when the curing rate growing fastest in different condition. The influence of the number of α-H in monomer and the monomer flow characteristics on oxygen inhibition was studied. The result shows that oxygen inhibition can be remitted by increasing the number of the ethyoxyls in monomer. Oxygen inhibition is related to the number of α-H and monomer viscosity.

Key words: UV-curing, UV-DSC, oxygen inhibition, α-H, viscosity
