Magnesium methacrylate (MgMA)/ hydrogenated nitrile rubber (HNBR) composites were prepared by blending MgMA with HNBR, and the effects of MgMA amount on mechanical properties of HNBR at high temperature and after immersion in drilling fluid were investigated. The results showed that under the combined action of high temperature and drilling fluid, the comprehensive performance of MgMA/HNBR composite was improved most significantly with higher tensile strength, elongation at break and tear strength, and the best thermal-oxydative aging resistance, when the amount of MgMA was 8 phr (mass).
