| 中文摘要: |
| 采用三维溶解度参数法、差示扫描量热法和物理性能分析法研究不同并用比的氯化聚乙烯橡胶（CM）/羧基丁腈橡胶（XNBR）并用胶的相容性。结果表明：XNBR和CM的三维溶解度参数分别为17.61和19.91 （J·cm-3）1/2，两种橡胶每一维度的溶解度参数均相差不大，不同并用比的并用胶均具有一定的相容性；随着XNBR用量的增大，并用胶物理性能改变，当XNBR用量为40～50份时，并用胶的物理性能变化趋势发生改变。 |

| The compatibility of CM/XNBR blends with different blend ratio was studied by three-dimensional solubility parameter method，differential scanning calorimetry and the physical properties analysis method.The results showed that，the three-dimensional solubility parameters of CM and XNBR were 17.61 and 19.91 （J·cm-3）1/2，respectively， and the solubility parameters of each dimension (dispersion，polar and hydrogen bonding) were very close，indicating that all the blends had certain compatibility.As the addition level of XNBR increased， the physical properties of CM/XNBR blends were changed，and the change trend turned different when it reached 40～50 phr. |
