Abstract
The effect of a commercial styrene/butadiene/styrene-based compatibilizer (Styroflex) on the tensile and impact properties of ternary blends of poly(acrylonitrile-co-butadiene-co-styrene) (ABS), high impact poly(styrene) (HIPS) and poly(ethylene terephthalate-cocyclohexanedimethanol terephthalate) (PETG) was investigated. The tensile yield strengths and the moduli of the blends were of similar magnitude as the parent polymers. However, notched Charpy impact properties showed significant deviations with high synergy in
ABS/PETG blends and strong antagonism in HIPS/PETG blends. Addition of Styroflex
improved the impact properties of all blends containing HIPS and ABS. Dynamic mechanical
analysis studies confirm the phase separated nature of ABS/PETG binary blends.
