520			_aThe purpose of the present research is to compare between the effect of different types of compatibilizers (maleic anhydride, epoxidized soybean oil and styrene butyl acrylate S-BA copolymer), which was added to overcome the incompatibility between NBR / EPDM blend, on the rheological, mechanical, physical and thermal properties of NBR / EPDM blends as well as to obtain the optimum amount of each type of them which will give such a superior properties. Blends of EPDM and NBR were prepared with different ratio (100 / 0, 75 / 25, 50 / 50, 25 / 75 and 0 / 100 EPDM / NBR) and the effect of the blend ratio on the mechanical, rheological and thermal properties have been investigated. Then compatibilization of 50/50 blend, which gives the superior mechanical properties, was made by using (MA) with ratios (0.5, 1, 1.5 and 2 phr); EO (2.5, 5, 7.5 and 10 phr) and S-BA (2.5, 5, 7.5 and 10 phr) were used, and a study of their effect on all the previous properties were made as well. It was found that, among different rubber blends, the (50 / 50) NBR / EPDM blend gives the highest rheological, mechanical and thermal characteristics. Using of MAH; EO or S-BA as compatibilizing agents increase the rheological, mechanical and swelling properties and at the same time don{u2019}t affect the thermal stability of the NBR / EPDM rubber blends. Finally, it is recommended, for the compatibilization of NBR / EPDM, to use 1phr MAH; 5 Phr EO or 5 phr S-BA as these amounts give the optimum rheological, mechanical and swelling properties for the NBR/EPDM rubber blends
