摘　　要：本文用DSC,WAXD,ESR和介电谱以及凝胶分数测定等技术,研究Nylon-1010的聚集态对γ-辐射化学反应以及辐照后热处理结果的影响。结果表明,辐照Nylon-1010的交联与裂解反应主要发生在非晶区或结晶表面,进一步证明了非晶区也是辐射后交联和后裂解主要反应区。The effects of aggregated state of nylon-1010 on the chemical reactions (crosslinking anddegradation) during gamma irradiation and on the effect induced by heat treatment afterirradiation have been studied by using DSC, WAXD, ESR and dielectric spectra, and gelfraction measurement techniques. It is concluded that the chain crosslinking and scission ofirradiated 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-degradationoccur.
