The compatibilizers used for those blends were methyl methacrylate-co-maleic anhydride (MMA-MAH) and MMA-co-glycidyl methacrylate (MMA-GMA). The ductile-brittle transition temperatures were found to be lower for blends compatibilized through maleate modified acrylic polymers. At room temperature, the PA6/ABS binary blend was essentially brittle whereas the ternary blends with MMA-MAH compatibilizer were supertough and showed a ductile-brittle transition temperature at -10°C. The blends compatibilized with maleated copolymer exhibited impact strengths of up to 800 J/m. However, the blends compatibilized with MMA-GMA showed poor toughness at room temperature and failed in a brittle manner at subambient temperatures.2643-2647engAcrylonitrile-butadiene-styreneBlendsCompatibilizationNylon 6ToughnessAminesComposition effectsCopolymersImpact testingNylon polymersOrganic acidsPhase transitionsPolymer blendsTemperatureCompatibilizersCompatibilizing agentsDuctile-brittle transitionsMaleated copolymersABS resinsmechanical propertynylon 6polymer blendArtigo10.1002/app.13013Acesso restrito2-s2.0-0242368821
