Abstract (en)
[origin: WO2005115707A1] A process is disclosed for crystallising amorphous polymers whose Tg lies below the crystallite melting point. According to this process, amorphous or partially crystalline polymer grains are exposed in water for a period of at least 30 seconds to a temperature in the polymer crystallisation range.
