Morphology and Properties of Amorphous Polyethylene Terephthalate
Physical and mechanical properties of amorphous polyethylene terephthalate (PET) have been measured. A uniform morphology was observed when PET thin film (ca. 1000 (ANGSTROM)) was ultraquenched from above its equilibrium melting temperature. Sufficiently rapid quenching rate below T(,g) and heating …
