Abstract
New polymeric nanocomposites based on nanostructured reinforcing agents as Polyhedral Oligomeric Silsesquioxanes (POSS) with methacrylic groups were synthesized and the influence of POSS type was studied. As polymer matrix a mixture of functionalized POSS and triethylene glycol dimethacrylate (TEGDMA) was used by replacing the classical diglycidyl methacrylate monomer (BisGMA) with various POSS functionalized with methacrylic groups. The obtained nanocomposites were characterized by spectroscopic methods (FT-IR, RAMAN), thermal analysis (TGA, DMA) and scanning electron microscopy (SEM). Keywords: polyhedral oligomeric silsesquioxanes, nanocomposite, thermostability, FT-IR, RAMAN, TGA, DMA, SEM
