考察了生物基聚酯弹性体/炭黑复合材料的耐油性能，并与丁腈橡胶/炭黑复合材料进行了对比。结果表明，常温下将生物基聚酯弹性体/炭黑复合材料分别浸泡在燃油（ RP-3）、润滑油（4109）及液压油（YH-15）中直至溶胀，其拉伸强度保持率分别达到了86.8％，88.5％，73.0％；在100℃以下，生物基聚酯弹性体/炭黑复合材料与丁腈橡胶/炭黑复合材料在经高温RP-3燃油处理后的力学性能保持率基本持平，而在100℃以上前者的力学性能保持率则明显优于后者。

The oil resistance of bio-based polyes-ter elastomers(BEE)/carbon black(CB) composites was investigated and compared with that of nitrile rubber ( NBR )/CB composite.The results showed that after soaking in fuel oil RP-3, lubricating oil 4109 and hydraulic oil YH-15 at room temperature to swelling respectively , the tensile strength reten-tion of BEE/CB composite reached 86.8%,88.5%and 73.0% in turn.When both BEE/CB and NBR/CB composite were soaked in fuel oil RP-3 for 24 h below 100 ℃, the mechanical properties reten-tion of the two composites was in the same level , but soaked over 100 ℃, the former was far better than the latter.
