| Abstract: |
| Acrylate rubber（ACM） and ethylene acrylate rubber（AEM） were used as compatibilizers，and their effects on the properties of mixed polyurethane rubber（MPU）/nitrile rubber（NBR） blends were studied.The results showed that adding compatibilizers ACM and AEM to MPU/NBR blends could promote the co-vulcanization of MPU and NBR，make the vulcanization characteristics between the two more compatible，and improve the compatibilities，physical properties，heat resistance and thermal oxygen aging properties of the blends.The compatibilizer AEM improved the performance of the blend better than the compatibilizer ACM.When the dosage of compatibilizer AEM was 20 phr，the two phases of the blend were completely compatible. |
