摘要: We have investigated the influence of hard spherical hydrophilic nanoparticles (fumed silica) on phase behavior PS/PVME (polystyrene/polyvinyl methyl ether) blend as a compatibilizer. The size is comparable to radius gyration polymers and particles preferentially segregate into one polymeric components. Phase separation was assessed using rheological analysis (RMS), differential scanning calorimetry (DSC), optical microscopy (OM). In order investigate kinetics in presence nanoparticles, time sweep experiments were employed via OM. A certain composition highly concerned shed light dynamic separation, unstable region diagram. diagram shifted up nearly 10 °C nanoparticles. Blends compatibilized by could provide an interesting economic alternative conven...
