| titleOfInvention | Preparation of hydrophilic nanoparticles by copolymerization of mono and divinyl monomers in micellar solution |
| abstract | The present invention relates to the preparation of hydrophilic nanoparticles and in particular hydrophilic nanoparticles that are biocompatible. Free radical monovinyl-divinyl monomer copolymerization/cross-linking reactions of water-soluble, monovinyl N-vinyl-2-pyrrolidone (NVP) with a bi-unsaturated divinyl, comonomer (poly{ethylene glycol}dimethacrylate) (PEGDMA), has been found to yield hydrophilic nanoparticles (NPs). These nanoparticles are built from three-dimensional nanopolymer networks. In the polymers' synthesis the composition of the monomers, and the total monomer concentration were varied. The characteristics of copolymers were determined by nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared (FTIR) and elemental analysis. Particle size and morphology of nanoparticles were confirmed by dynamic light scattering (DLS), transmission electron microscope (TEM) and scanning electron microscope (SEM) methods. In the present invention hydrophilic polymers can be used in micellar polymerization to create hydrophilic nanoparticles. |
