Key Engineering Materials, 2005
In this paper, polyethylene glycol (PEG) of various different molecular weights was grafted onto PET films using plasma surface grafting modification. The surface structure of PEG-grafted PET films was analyzed by attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS), suggesting that ...

Polyphenylene ether (PPE)/glycol modified polyethylene terephthalate (PETG) blends with various compositions were fabricated via a melt blending method using a laboratory-scale twin-screw extruder. The fracture surface morphology of the PPE/ PETG blends was examined by scanning electron microscopy (SEM) and, based on its data, it was observed that PPE ...

Biomaterials, 1998
Although biocompatible polymeric compounds are generally nontoxic, nonimmunogenic, and chemically inert, implants made from these materials may trigger acute and chronic inflammatory responses. These inflammatory reactions may induce degeneration of implanted biopolymer.

The kinetics of diethylene glycol formation in the preparation of polyethylene terephthalate
Journal of Polymer Science Part A: Polymer Chemistry, 1998For revealing diethylene glycol (DEG) formation in poly(ethylene terephthalate) (PET) synthesis, this research focused on finding the stage most critical for DEG formation. It is found that the esterification stage was the most critical stage for DEG formation during production of PET through the direct esterification process. In addition, the kinetics

3D and 4D Printing of Polyethylene Terephthalate Glycol–Polypropylene Blends
Journal of Applied Polymer ScienceABSTRACTPolypropylene is one of the most widely used industrial thermoplastics, which, despite its high consumption in various industries, especially packaging, is not used much in the emerging field of 3D printing. In this article, for the first time, PETG is used in three weight percentages of 55%, 70%, and 85% to enhance polypropylene's printability,
