| Abstract: | Radiation effects on polyamide-1010 specimens having various states of aggregation were studied using wide angle X-ray diffraction, electron spin resonance, calorific and sol measurement techniques. Experimental results indicated that chain crosslinking and scission of the irradiated polyamide-1010 occurred mainly in the amorphous region and on the crystal surface. The radiation-induced crystal damage and amorphotization started from the crystal surface (or interface) and extended into the inner portion of the crystal with increasing radiation dose. It is believed that the interface between crystalline and amorphous regions was the main region wherein free radicals were trapped. |
