Abstract
The present disclosure concerns embodiments of a polymeric compound, embodiments of a method for making and using the disclosed polymeric compound, and embodiments of a polymerizable composition. The polymeric compound is formed via photopolymerization of a photoinitiator and various polymerizable monomers. The disclosed polymeric compound and its components are useful as biomaterials, photolithography, and other applications. In particular disclosed embodiments, the photoinitiator comprises one or more chromophores capable of absorbing energy at particular wavelengths suitable for promoting formation of a carbanion capable of reacting with a polymerizable monomer.
