Beschreibung
Zusammenfassung:	The present invention relates to a method, which is capable of crystallizing crystalline particles of thermoplastic materials while isolating low molecular weight contents contained in the thermoplastic materials. The method is preferably characterized in that the crystallization stage and the separation stage are conducted at different particle temperatures. The invention also relates to an apparatus used for carrying out the aforementioned method.
