High Molecular weight nano/micron sized polystyrene (Mv=1X106) was prepared by styrene and hydrogen peroxide. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) measurements indicated that the particles matched with that of the polymer single chain. The same chemical structure of both nano/micron and bulk polystyrene was confirmed by means of FTIR spectroscopy studies. Thermal analysis indicated that nano/micron sized particles exhibited a significantly higher glass transition temperature (Tg) than bulk particle.
