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.
