The TEMSCANIEM 100C apparatus has been applied in the observation of spherulitic structure of bulk polypropy­lene samples (PD 161 grade of Hercules) etched with chro­mic mixture. A combination of the Kato and Williams-Hud­son methods has been used. The optimum composition of the etching solutions has been established and a high quality of patterns has been stated in recompense for the long du­ration of the process.
