Free radical polymerization enamel

Furthermore, monomers for restorative composites or composite cements should exhibit a low volume contraction during polymerization, excellent mechanical properties after polymerization, and low water solubility. The water sorption of the formed polymer should also be low. The currently used direct restorative composites, composite cements, and enamel/dentin adhesives are largely based on methaciylate chemistiy using mixtures of different methacrylates, such as crosslinking and functionalized methacrylates, which can be cured by free-radical polymerization. ...
