Cationic photoinitiator

Cationic photoinitiators include diazonium salts, diaryliodonium salts, triarylsulfonium salts, alkylsulfonium salts, iron arene salts, sulfonyloxy ketones, and triarylsiloxane ethers. Its basic function is that photoactivation makes the molecule to the excited state, and the molecule undergoes a series of decomposition reactions, and finally produces a super protonic acid (also called Bronsted acid), which is used as an active species for cationic polymerization to initiate epoxy compounds, vinyl ethers , Polymerization of lactones, acetals, cyclic ethers, etc.
