As the waste of Acrylonitrile-Butadiene-Styrene (ABS) increases, recycling of ABS is important to reduce environmental issues. However, the properties of recycled ABS (r-ABS) deteriorate due to thermal oxidative aging during its lifetime. The resin undergoes aging effects, especially at polybutadiene. Due to aging effects, the materials become brittle and impact strength decreases sharply. In this work, as an impact modifier and compatibilizer, styrene-butadiene-styrene (SBS) was used to improve the impact strength. Also, plasma-assisted mechanochemistry (PMC) process was introduced to improve dispersion of SBS and compatibility between r-ABS and SBS. We confirmed that the mechanical properties of r-ABS have been improved to achieve those of virgin ABS.
