| Abstract: |
| The effect of addition level of sulfur on the shape memory property of eucommia ulmoides gum was investigated. When the addition level of sulfur increased，the ML of the compound changed little， the MH increased， and the t90 was shortened at first and then extended.Meanwhile，the crosslink density of the vulcanizates tended to increase，the modulus and tensile strength decreased at first and then increased，the thermal stimulation response temperature tended to decrease，and the final deformation recovery rate increased at first and then decreased.When the addition level of sulfur was 1 phr，the physical properties and thermal induced shape memory property of the vulcanizates were the best. |
