Photoinduced cross-linking polymerization of monofunctional vinyl monomer without conventional photoinitiator and cross-linker

A study was conducted to demonstrate strategies that performed photoinduced cross-linking polymerization of monofunctional vinyl monomer, without conventional photoinitiator and cross-linker. The technique was most widely employed in coating industries, as vinyl monomers were effectively polymerized with the method. The strategies for photoinduced cross-linking were divided into two stages, such as one-stage crosslinking of of multifunctional monomers or copolymerization with difunctional monomers and two-stage cross-linking through polymers possessing photosensitive sites. A set of structurally designed bisbenzodioxinones was used in the polymerization process that liberated both the photoinitiator and cross-linker after simulation by light.
