【発明の名称】熱可塑性縮合重合体を処理する方法と装置
Document Type and Number:
Japanese Patent JP2002531285
Kind Code:
A
Abstract:
Method and device for reprocessing a thermoplastic polycondensate, in particular for the recycling of thermoplastic polycondensates, such as polyethylene terephthalate, polyester or polyamide is provided. The polycondensate is introduced into an extruder in a solid state. The polycondensate is then heated to a temperature below melting temperature and degassed or dried at below atmospheric pressure or with an inert gas added. Preferably, to prevent the polycondensate flakes from escaping through a degassing opening, a conveying device is used to convey the escaping flakes back into the extruder. The dried flakes are then melted.
