| Abstract: |
| A study was made on the application of dimethyl silicone oil，propanetriol and 1，2-propanediol to decrease the modulus of MVQ vulcanizate. The results showed that the modulus of MVQ vulcanizate decreased with dimethyl silicone oil while the tensile set and compression set increased；the influence of propanetriol on the properties of MVQ was related to the structure control agent，for example，diphenyl silandiol rather than hydroxyl silicone oil was a suitable structure control agent for propanetriol to decrease the modulus of MVQ vulcanizate；the modulus of MVQ vulcanizate could be significantly decreased by 1，2-propanediol and the excellent physical properties and heat aging resistance of vulcanizate could be obtained. |
