Abstract: The effects of maleic anhydride (MA) and triallylisoeyanurate (TAIC) on the structure and properties of PPC/NBR elastomers have been examined. Dynamic mechanical and TEM results showed that MA or TAIC can effectively improve the cross-linking structure of the elastomers. The mechanical properties and thermo-oxidative resistance of the elastomers were greatly improved by adding MA;Addition of TAIC increased the oil resistance and the mechanical properties of PPC/NBR elastomers.
