PECULIARITIES OF GRAFT POLYMERIZATION INITIATED FROM THE PEROXIDIZED SURFACE OF MINERAL NANOPARTICLES

The peculiarities of graft polymerization of different nature vinyl monomers initiated from the surface of SiO2, Fe3O4, and hydroxyapatite nanoparticles modified by peroxide-containing copolymers were studied. It was shown that the developed surface of NPs has a significant effect on the kinetics of the polymerization process. The order of polymerization rate with respect to initiator concentration is equal to 0,58.

NANOCOMPOSITE HYDROGELS WITH EMBEDDED MINERAL NANOPARTICLES

Cross-linked nanocomposite hydrogels based on poly(acryl amide) and mineral nanoparticles (NP) of hydroxyapatite (HAP), ZnO, TiO2 modified by reactive polymers were synthesized via the technique of polymerization filling. It was shown that physico-mechanical properties of obtained nanocomposites are determined to a great extend by the nature of the modifier of mineral NP.
