摘　　要：用ＤＳＣ以及凝胶含量测定的方法研究了辐照聚酰胺１０１０的后效应，讨论了晶区分子运动与转变受辐射后效应的影响，也探讨了结晶表面积对后效应的影响。结果表明辐射后效应主要来源于结晶表面内的俘陷自由基。Post radiation effects on polyamide 1010 were studied by DSC and the determination of gel fraction. The transition and relaxation of macromolecules in the crystalline phase imposed on by post radiation effects of polyamide 1010 were also investigated. Futhermore, the influence of the fold surface on post radiation effects was focused on. The results showed that the trapped radicals in the fold surface attributed to postradiation effects. The more the amount of the fold surface of the lamellae is, themore profound post radiation effects on polyamide 1010 show.
