Abstract
Cyclic N-vinylamides were found to increase the maximum relative rates of photopolymerization of hexanedioldiacrylate formulations at low light intensities under nitrogen and dramatically under air, while acyclic N-vinylamides and cyclic N-alkylamides were found to have much smaller, though still significant, effects in air. The combination of the cyclic aliphatic amide and N-vinylamide functionalities generally resulted in the maximum benefit for reduction of oxygen inhibition resulting in rapid rates of polymerization in air at low light intensities. While the complete mechanistic explanation of the rate enhancement is still unclear, several possible mechanistic pathways are discussed.
