In vivo and in vitro responses to poly(ethylene terephthalate-co-diethylene glycol terephthalate) and polyethylene oxide blends

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, 1998
For 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 Science
ABSTRACTPolypropylene 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,

Mechanical Interlocking of Polypropylene-Based 3D-Printed Structures with Polyethylene Terephthalate Glycol Inclusions

ACS Applied Materials & Interfaces
We report on enhancing the mechanical and structural characteristics of polypropylene (PP) three-dimensional (3D)-printed structures fabricated via fused filament fabrication (FFF) by employing hybrid PP-based filament containing a minute amount of polyethylene terephthalate glycol (PETG) inclusions.
