WebIn the present work, we investigate the viability of a thiol-acrylate-epoxy sequential dual-curing system where both reactions are activated using a single thermal catalyst. This system relies on the faster curing kinetics of the thiol-acrylate Michael addition compared to the thiol-epoxy reaction. We expect the thiol- WebPhotopolymerization behavior of thiol–ene system The samples of allyl-terminated benzoxazine with 10, 30, and 50 wt % SH-POSS were separately dissolved in CHCl

Thiol-Ene Step-Growth as a Versatile Route to Functional

WebThiol−isocyanate−ene ternary networks with systematic variations (100/100/0, 100/80/20, 100/60/40, 100/40/60, 100/20/80, and 100/0/100) were prepared by sequential and simultaneous thiol−ene and thiol−isocyanate click reactions. The thiol−isocyanate coupling reaction was triggered thermally or photolytically to control the sequence with the … WebCatalyst reactivity – Although other peroxides are appropriate, the catalyst most often used tocure silicone PSAs is benzoyl peroxide (BPO).
