Efficient stabilization of thiol-ene formulations in radical photopolymerization

Efficient stabilization of thiol-ene formulations in radical photopolymerization

Various phenolic radical inhibitors were tested to improve storage stability of thiol‐ene formulations. After determining the optimal inhibitor, a synergetic effect was discovered when it was used in combination with acidic buffer, thus preventing premature dark gelation while maintaining desired ph...

Zusammenfassung:Various phenolic radical inhibitors were tested to improve storage stability of thiol‐ene formulations. After determining the optimal inhibitor, a synergetic effect was discovered when it was used in combination with acidic buffer, thus preventing premature dark gelation while maintaining desired photoreactivity.
