  • Patent number: 8932404
    Abstract: The present invention relates to a method for producing semicrystalline polymer material, wherein the predominantly amorphous raw polymer material, in particular granules, to be treated is introduced into a crystallization reactor (1) and is partially crystallized there by being heated, but without melting, and subsequently the semicrystalline polymer material obtained in such a way is removed from the crystallization reactor (1) and at least part of said semicrystalline polymer material is diverted and mixed back into the crystallization reactor (1) in order to reduce the adhesive tendency of the polymer material. According to the invention, the diverted semicrystalline polymer material is combined and mixed with the raw polymer material before being mixed back into the crystallization reactor (1), and the mixture is then introduced into the crystallization reactor (1).
