and those reactively compatibilized by the addition of imidized acrylic polymer (IA) or styrene/acrylonitrile/maleic anhydride terpolymer (SANMA). Nylon 6/SAN blends can be considered as a simpler version of industrially important polyamide (PA)/ABS blends; therefore, this study is useful for the better understanding of diminishing dispersed phase particles for PA/ABS blends with compatibilizers
