The radiation effects on the polyamide 1010 samples of various aggregation states and the crystal damage induced by irradiation have been investigated by WAXD and SAXS techniques,The results indicated that the cross-linking and scission of the irradiated polyamide 1010 samples occurred mainly in the amorphous region and interphase (or crystal surface) and the crystal damage induced by irradiation started from crystal surface,extending into the inner portion of the crystal with increasing radiation dose.The portion of irradiation damage for the (010) plane is greater than that for the (100) plane.The post-radiation effects induced by heat-treatment,a further crosslinking and scission affect the formation and perfection of the (010) plane and cause a decrease of crystallite size L100 and the cryst-sllinity of the samples.
