| 中文摘要: |
| 采用平衡溶胀法和粘度法分别测定了甲基乙烯基硅橡胶(MVQ)的溶解度参数。采用平衡溶胀法测定时，交联高聚物的溶解度参数与溶剂的溶解度参数相等时，交联高聚物的溶胀比Qv值最大，其所对应溶剂的溶解度参数即为高聚物的溶解度参数，求得MVQ的溶解度参数δQ为15.65 (J·mL-1)1/2。采用粘度法测定时，不同溶剂溶解高聚物所得溶液的特性粘度最大值所对应溶剂的溶解度参数即为高聚物的溶解度参数，求得MVQ的溶解度参数δQ为15.78 (J·mL-1)1/2。可以看出，两种方法测得的数据十分相近，说明这两种测定方法实用可行。 |

| 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. |
