METHOD FOR CRYSTALLIZATION AND SEPARATION OF LOW-MOLECULAR COMPONENTS FROM A GRANULATE OF A CRYSTALLIZABLE THERMOPLASTIC MATERIAL AND DEVICE THEREFOR

摘要

The present invention relates to a method which allows the crystallization of a granulate of a crystallizable thermoplastic material and at the same time the separation of low molecular components which are contained in the thermoplastic material. The method is characterized in that the crystallization step and the separation step are carried out at different temperatures of the granulate. The present invention further relates to a device for carrying out the aforementioned method.
