Polyethylene terephthalate (PET) is one of the most widely used polyesters today - it is used in packaging, fabric, engineering, electronics, and biomedical industries. Different methods for PET molecular weight determination are reviewed in this chapter. Molecular weight is the most important characteristic for determining the mechanical properties and ability to fabricate these materials for different applications. Experiences and several recent findings from the authors' laboratory are also included for forensic PET fiber comparison and PET molecular weight analysis. Finally, a few recent applications utilizing PET are reviewed, focusing on biomedical research such as the next generation of PET fibers, high-tenacity polyester fibers (HT PET), and PET clay nanocomposites.
