Abstract

Abstract: The effect of gamma-irradiation on the state of aggregation of nylon 1010 was studied by using WAXD and DSC techniques. The results showed that the crystal damage and amorphotization induced by gamma-irradiation are closely related to the chemical reaction of atoms on the interface between crystalline and non-crystalline region of the polymer. The damaging started from the surface of the crystal and proceeded gradually into the crystal, which became completely amorphous when radiation dose was extremely high.

Key words: Nylon 1010, gamma-ray irradiatiom, aggregated state, radiation crosslinking, WAXD, DSC
