among cationic polymerization photoinitiators, onium salts account for the major share
photoinitiators can be divided into free radical polymerization photoinitiators and cationic polymerization photoinitiators according to different initiation mechanisms. among cationic polymerization photoinitiators, onium salt cationic polymerization photoinitiators are the most used. onium salt cationic polymerization photoinitiators refer to a type of photoinitiator products containing onium salt cations. onium salts refer to some organic matter containing oxygen, nitrogen or sulfur that can dissociate into organic cations in…
