Thermo‐Mechanical and Structural Characterization of Isothermally Annealed 3D Printed Pseudo‐Amorphous Polyetherketoneketone (PEKK).

Macromolecular Materials and Engineering
Polyetherketoneketone (PEKK) (60/40 TERE/ISO) is characterized by a lower processing temperature and a higher glass transition temperature (Tg) compared to polyetheretherketone (PEEK), making it a promising material for 3D printing.
