| Abstract: |
| The curing characteristics， morphology，dynamic and physical properties and low temperature tensile strength of ethylene-vinyl acetate rubber（EVM）/hydrogenated nitrile-butadiene rubber(HNBR) blends prepared by melt blending were investigated.The results showed that EVM formed the continuous phase and HNBR was the dispersed phase when the blending ratio of EVM/HNBR was 70/30.HNBR could become continuous phase with the increase of HNBR mass fraction. The low-temperature resistance of EVM was improved with the addition of HNBR.When the blending ratio of EVM/HNBR was 70/30， the elongation at break at -40 ℃ was around 300%.Differential Scanning Calorimeter analysis also indicated that the glass transition temperature of the blends shifted toward low temperature with increasing HNBR mass fraction. |
