Dear friends, why use tetraethylmethane ketone as photoinitiator (5wt% of photomonomer added), triethanolamine as co-initiator, UV-induced (light wavelength 365nm) acrylamide double bond polymerization, Why can't do photopolymerization?

Hello Sa, tetraethylmethane ketone probably does not absorb light at 365nm. This could be observed on its UV absorption spectra. Pick a photoinitiator that absorbs light at 365 nm.

If you still want to use tetraethylmethane ketone, you need to use lower wavelength light which will be absorbed by the photoinitiator.
Also because your monomer concentration is low, be sure to remove oxygen to prevent quenching.
