Novel addition-fragmentation agent in cationic photopolymerization

Exploring the benefits of β-allyl sulfones for more homogeneous dimethacrylate photopolymer networks

“…25 Some studies were also done using AFCT chemistry for the acceleration of cationic photopolymerization. [26][27][28] Very limited work has been performed on AFCT reagents as additives for the synthesis of highly cross-linked materials. 29,30 Therefore, we have recently introduced β-allyl sulfones as potent AFCT reagents for dimethacrylate resins.…”

Recent advances in applications of vinyl ether monomers for precise synthesis of custom-tailored polymers

“…[137]. A number of recently introduced photoinitiating systems comprise functionalized carbazoles [141,142], pyrenes [143], di-and polythiophenes [144] and disulfones [145], C 60fullerene [146], allylic ammonium or phosphonium salts [147,148], acylgermanes [149] or different dyes [150,151] Scheme 21. Examples of photocatalysts that promote photocontrolled cationic polymerization.…”
