The current invention is a novel composition of matter that is comprised of a monomeric species, which could be used as co-initiator as well as co-monomer. Upon excitation using visible light, the monomeric species efficiently assists the photopolymerization and itself polymerizes into a material that is useful for dental applications.
The compound of the invention is used in conjunction with two other compounds widely used in the dental polymer field. The system is irradiated with visible light and the system polymerizes and hardens to form a material suitable for dental applications.
The current invention prevents amine leaching from resulted polymers. The polymer forms with a comparable degree of conversion as known co-initiators.
The good chemical stability and comparable degree of conversion prevent amine leaching from polymers and offer higher relative crosslinking density for polymers when it was used as co-monomer. The slower kinetics of the current invention might reduce the polymerization shrinkage.
The compound, as a polymer, can be used in any field in which a polymeric substance that decreases polymerization shrinkage and prevents amine leaching might be useful.
