Nanocomposites based on a mixture of poly(ethylene glycol) dimethacrylate (PEGDM) with poly(ethylene glycol) monomethacrylate (PEGMM) (mass ratio 1:1) and propyl methacrylate functionalized polyhedral oligomeric silsesquioxane (M-POSS) were obtained by photopolymerization. Both the polymerization kinetics of compositions (with M-POSS contents loadings between 0 and 100 wt. %) and mechanical properties (with M-POSS contents between 0 and 35 wt. %) were investigated. It was found that M-POSS addition accelerates or retards the polymerization, depending on its concentration and reduces double bond conversion, however significantly increases modulus (E), tensile stress (σM) and hardness (H) of the resulting nanocomposite.
