摘要
采用红外光谱(FTIR)、核磁共振氟谱(;F-NMR)对氟醚橡胶的分子结构和单体组成进行了分析和估算,通过热失重分析(TGA)和差示扫描量热法(DSC)对其与常规F246氟橡胶的热学性能进行了测试对比,明确了氟醚橡胶的组成结构和热学性能。
The molecular structure and monomer composition of fluoroether rubber were analyzed and estimated by infrared spectroscopy(FTIR) and nuclear magnetic resonance fluorine spectroscopy(;F-NMR).The thermal properties of fluoroether rubber were tested and compared with that of conventional F246 fluororubber by thermogravimetric analysis(TGA) and differential scanning calorimetry(DSC), and the composition structure and thermal properties of fluoroether rubber were clarified.
