| 摘 要： | 室温时空气中辐照F-40样品中残存有链侧和链端过氧化自由基,这些自由基在室温下衰变缓慢.DSC研究表明,F-40样品熔融温度Tm随辐照剂量的增加而下降,本文用聚合物片晶熔融的一般模型加以解释.

| Abstract: | The-mid-chain and end-chain peroxyl radicals are trapped in the samples irradiated in air at room temperature. They decay slowly at room temperature. It was indicated by means of DSC technique that melting temperature Tm of irradiated F-40 decreases with the increasing radiation dose. This fact was interpreted in terms of the general model of lamellar crystallites. |

| Keywords: | Radiation crosslinked F-40 Radical decay ESR DSC |
