| Abstract: | In this paper,the application of the Dynamic Mechanical Thermal Analyzer on the research of the natural rubber(NR) was introduced.The dynamic mechanical property of the NR and modified-NR at low temperature was studied by DMA.The parameters of dynamic mechanical property of NR samples were tested.The authors calculated the fragility parameters of the samples based on the time-temperature superposition principle of dynamic mechanical performance and the constants C1 and C2 of the WLF equation. |
