Fig. 5. Photopolymerization profiles (glycidyl group conversion vs. irradiation time) of DEGBA/EPXPROP (70%/30% w/w) monomers in the presence of a photoinitiating system based on biphenyl derivatives and bis-(4-t-butylphenyl)iodonium hexafluorophosphate (0.1/1% w/w) under irradiation of vis-LED @ 365 nm (16.27 mW cm⁻²).
