| Abstract: |
| The solubility parameter of methyl vinylsilicone rubber(MVQ) was determined with the equilibrium swelling method and the viscosity method respectively.When the equilibrium swelling method was used and if the solubility of the polymer was equal to that of the solvent，the swelling ratio of the crosslinked polymer Qv was maximum，the corresponding solubility parameter of the solvent was the solubility parameter of the polymer and the obtained solubility parameter of MVQ δQ was 15.65 (J·mL-1)1/2.When the viscosity method was used，the solubility parameter of the solvent correspounding to the maximum characteristic viscosity of the polymer solution with different solvents was the solubility parameter of the polymer，and the obtained solubility parameter of MVQ δQ was 15.78 (J·mL-1)1/2.It was found that the two methods were practical because the results from them were very close. |
