  • Crystallized polyethylene terephthalate, which contains silicon, and process for its preparation
    Patent number: 7989558
    Abstract: The present invention is directed to crystallized polyethylene terephthalate, PET, which contains silicon in a bounded M and integrated into the molecular structure of PET form. The crystallized form preferably has been obtained by a temperature treatment of amorphous PET, which contains silicon in a bounded and integrated into the molecular structure of PET form. There is also described a process for the preparation of crystallized polyethylene terephthalate, PET, which contains silicon in a bounded and integrated into the molecular structure of PET form.
