Abstract

Viscosities and phase behavior of polystyrene – organic hybridized silica nanoparticle at 270 °C were measured with a newly developed visible windows equipped rotational viscometer. The improvement of selection and mounting for the rotary shaft coupling decreased the fluctuation of viscosity measurements. Organic hybridized silica nanoparticles were obtained by treating phenyltrimethoxysilane and silica nanoparticle. The formation of organic hybridized silica nanoparticles were confirmed by using TG-DTA and FT-IR. The viscosities of polystyrene – organic hybridized silica nanoparticles were increased with the mass fraction of the organic hybridized nanoparticles, because the melting point of the blend polymer was increased with the mass fraction of the organic hybridized nanoparticles. The phase behavior of the polystyrene – organic hybridized silica nanoparticle were carried out by the view window, however, no homogeneous states of the blend polymer were found due to the increase of the melting point and the lack of heating temperature. In the future work, we have to optimize the melting temperature and equilibration time for the polystyrene – organic hybridized silica nanoparticle system.
