Melting and Recrystallization of Irradiated Polyethylene

Laboratory of Polymer Physics, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchu, 130022

Received Date: 18 January 1995
Revised Date: 28 April 1995

The behaviour of melting and recrystallization of irradiated polyethylene has been investigated by using differential scanning calorimetry(DSC),small angle X-ray scattering(SAXS) and wide angle X-ray diffraction (WAXD) techniqties. It is indicated that the crys-talline structure of polyethylene was damaged and both apparent heat of fusion and crys-tallinity redticed with increasing radiation dose. After the irradiated polyethylene was melted and then recrystallized,the recrystallinity and melting temperature decreased with radiation dose.
