Abstract

Abstract: The behaviour of melting and recrystallization of irradiated polyethylene has beeninvestigated 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 meltedand then recrystallized,the recrystallinity and melting temperature decreased with radiationdose.

Key words: polyethylene, irradiation effect, differential scanning calorimetry, small angle X-ray scattering, wide angle X-ray diffraction
