✦ Synopsis

In the present work we attempt to settle the controversy on the district wherein the radiation induced reaction preferentially occurs through examining the structural changes of the irradiated polyamide-1010 specimens on both the crystallographic and the supermolecular level by using WAXD and SAXS techniques. Experimental results indicated that the chain crosslinking and scission of the irradiated specimens occur mainly in the amorphous region and on the crystal surface (or interphase), and extend into the inner portion of the crystal with increasing radiation dose.
