摘　要：研究了反式聚异戊二烯橡胶(TPl)/NBR并用胶的耐油性能和力学性能，以及用TPI-接枝-甲基丙烯酸甲酯(TPI-g-MMA)对并用胶进行的相容改性。研究结果表明，TPI/NBR并用胶耐油性能很好，但力学性能较差；TPI-g-MMA可明显改善TPI和NBR两相之间的相容性；加入TPI-g-MMA相容的TPI/NBR并用胶保持了很好的耐油性能，且力学性能明显改善。

Abstract：The oil resistance and mechanical properties of TPI/NBR blends and the use of TPIgraft-MMA as the compatibilizer of blends were investigated. The results showed that the oil resistance of TPI/NBR blends was very good, but their mechanical properties were quite poor; the compatibility between TPI and NBR improved significantly by adding TPI-graft-MMA; the improved mechanical plopeniesof compatibilized blends were obtained without sacrificing their oil resistance.
