The effects of aggregated state of nylon-1010 on the chemical reactions (crosslinking and degradation) during gamma irradiation and on the effect induced by heat treatment after irradiation have been studied by using DSC, WAXD, ESR and dielectric spectra, and gel fraction measurement techniques. It is concluded that the chain crosslinking and scission of irradiated nylon-1010 occur mainly in the amorphous region or crystal surface, and the non-crystalline region is also the main district where tbe post-crosslinking and post-degradation occur.
