Rezumat:

New polymer inorganic-organic nanocomposites based on polyvinyl acetate were
synthesized. Two types of compounds: mesoporous silica and a modified zeolite (HZSM-5)
were used as inorganic matrix. The radical polymerization of the vinyl monomer took place
in the pores of the inorganic structure. The raw materials were analyzed by chemical
quantitative analysis and dynamic light scattering (DLS). In order to prove the
nanocomposite obtaining, the final products were characterized by Fourier transform
infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) for chemical
structure, X-ray diffraction (XRD) for crystallinity, scanning electron microscopy (SEM)
for microstructural analysis and differential scanning calorimetry (DSC) for thermal
transitions assessment.
