Abstract: Polystyrene polycrystals have been obtained by quick cooling treatment of the dilute solution of random polystyrene in cyclohexane using liquid nitrogen.The results of transmission electron microscope and X-ray diffraction have shown that the polystyrene polycrystals belong to hexaplanar and its amount is about 20% of the total.
