A　new　way　has　been　devised　to　modify　acrylonitrile-butadiene-styrene　(ABS)　using　maleic　anhydride　(MAH)　functionalized　ABS　and　ethylene-propylene-diene　rubber　(EPDM)　as　compatibilizer　and　flexibilizer.　The　SEM　micrographs　and　electrical　analysis　reveal　that　EPDM-g-MAH　shows　poor　compatibility　with　ABS　matrix,　but　the　polymer　blends　become　much　more　miscible　after　being　compounded　with　ABS-g-MAH.　Carbon　black　(CB)　selectively　dispersed　in　ABS　phase　increases　the　concentration　of　CB　in　ABS　domain,　which　dramatically　increases　electrical　conductivity.　Moreover,　with　raw　ABS　being　massively　added　into　the　blends,　the　mechanical　properties　are　significantly　improved　while　conductivity　is　slightly　decreased.　©　2014　Elsevier　B.V.　All　rights　reserved.
