We studied polymeric nanoparticles made of poly(methylmethacrylate) and of polystyrene dispersed in water. We observed the formation of well defined nanoparticles by light scattering, small-angle neutron scattering (SANS), and cryogenic transmission electron microscopy (Cryo-TEM) methods. The study shows how nanoparticle properties are changed by the chemical composition of surfactants, molar mass of polymers, concentrations of both components. Dynamic light scattering (DLS) and static light scattering (SLS) provide the hydrodynamic radii and radii of gyration, cryo-TEM experiments prove that the nanoparticles have good spherical shape. Analysis of SANS data and cryo-TEM micrographs suggest that the prepared particles are composed of polymer and surfactant that are evenly distributed.
