10 Morphology of Free-Volume Holes in Amorphous Polymers by Means of Positron Annihilation Lifetime Spectroscopy (Giovanni Consolati and Fiorenza Quasso).
SUMMARY A review of the theory and experience of Positron Annihilation Lifetime Spectroscopy in polymers provided strong evidence that the longest lived annihilation mode occurs in the free volume sites located in amorphous polymers and the amorphous regions of semicrystalline polymers.
Previous studies of uncompatibilized linear low-density polyethylene (LLDPE)/isotactic polypropylene (PP) binary blends have been reported by the authors using techniques such as positron annihilation lifetime spectroscopy (PALS), small angle X-ray scattering (SAXS), density measurements, differential scanning calorimetry (DSC), tensile testing, and Charpy impact testing (1-3).
