Synthesis and characterization of a series of hydrophilic polymer nanoparticles prepared via emulsion polymerization technique

A series of hydrophilic polymer nanoparticles composed of methyl methacrylate (mma),methacrylic acid (maa) and 2-hydroxyethyl methacrylate (hema) monomers were successfully prepared via emulsion polymerization technique. the effects of different surfactant concentrations towards the particles size of polymer nanoparticles have been discussed. the hydrophilic polymer nanoparticles had mean diameters in the range of 100 - 270 nm depending on the reaction conditions and most of the polymer nanoparticles were obtained as spherical-like shape determined by scanning electron microscopy (sem). the formation of hydrophilic polymer nanoparticles were confirmed by fourier transform infrared (ftir) spectroscopy and in turn,simple solubility test was conducted in order to confirm the hydrophilicity of polymer nanoparticles. © 2017 penerbit umt.
