To decrease the toxicity and improve the photopolymerization process, the nanocomposite materials based on polyhedral oligomeric silsesquioxane (POSS), are an alternative because of the unique features derived from the introduction of appropriate functionalities in the organic branches, in addition to its biocompatible property. The present study describes the synthesis of amine-functionalized silsesquioxanes (SSQO) as coinitiator and the characterization of materials prepared from a dimethacrylate monomer modified with the synthesized SSQO.
