| 中文摘要: |
| 研究9种防老剂单用和并用对树脂级低顺式聚丁二烯橡胶（LCBR）性能的影响。结果表明：在9种防老剂中，单独使用防老剂1010、防老剂1520和西尼尔6308的防老化效果较好；复合使用防老剂时，防老剂1010/TNPP和防老剂1520/TNPP并用体系的防老化效果较好；当防老剂1010/TNPP并用比为80/20或防老剂1520/TNPP并用比为70/30时，LCBR的耐热氧老化性能最佳；防老剂1010/TNPP和防老剂1520/TNPP并用体系均能提高改性树脂HIPS和ABS的物理性能。 |

| Effects of single and combination use of nine kinds of antioxidants on the properties of low cis-1，4-polybutadiene rubber（LCBR）were investigated. The results showed that，in the nine kinds of antioxidants，the anti-aging effects of antioxidant 1010，1520 and 6308 were good when being used alone，and the anti-aging effects of the antioxidant 1010/TNPP and antioxidant 1520/TNPP systems were good when being used in combination. When the blending ratios of antioxidant 1010/TNPP and antioxidant 1520/TNPP were 80/20 and 70/30，respectively，the thermal oxidative aging property of LCBR was the best. Antioxidant 1010/TNPP and antioxidant 1520/TNPP systems could improve the physical properties of HIPS and ABS modification resins. |
