Toughening and Compatibilization of Acrylonitrile–Butadiene–Styrene/Poly (Ethylene Terephthalate) Blends

Abstract

The blends of acrylonitrile-butadiene-styrene (ABS)/poly (ethylene terephthalate) (PET) compatibilized by styrene maleic anhydride (SMA) and toughened by ABS high glue powder (ABS-HGP) were prepared by extrusion and injection molding. Adding SMA, the Izod impact strength, elongation at break, viscosity and Vicat temperature of blends were improved. Differential scanning colorimeter showed ABS and SMA hindered the crystallization process of PET and scanning electron microscopy (SEM) showed the domain size of PET in compatibilized blends became small and the distribution appeared to be uniform. ABS-HGP can toughen ABS/PET/SMA blends well.Adding 20 wt% ABS-HGP, the Izod impact strength of the blends improved from 8.9 KJ/m 2 to 18.6 KJ/m 2 and elongation at break increased from 38.9% to 76.1%. The viscosity of blends was increased a lot because of high glue powder. SEM showed the cavitation of rubber particles was the major toughening mechanism in ABS/PET/SMA/ABS-HGP blends.

Blends of recycled polycarbonate and acrylonitrile-butadiene-styrene: comparing the effect of reactive compatibilizers on mechanical and morphological properties

“…Also, excess MA and dicumyl peroxide in the compatibilizers may remain during the grafting reaction that produces these compatibilizers. So, MA can react with the butadiene of ABS to produce a block or graft copolymer during melt blending in the extruder, these two copolymers being able to increase the interfacial strength …”

Effect of acrylonitrile–butadiene–styrene/polyethylene terephthalate blends on dimensional stability, morphological, physical and mechanical properties and after aging at elevated temperature

“…The ABS low thermal stability required a longer thermal curing period which caused decreased productivity or increased investment costs. 5,36,37 Adding PET into the ABS phase with its elongated PET fibrils parallel to the FD might act as reinforcing agents and so compensate the ABS phase stress relaxation resulting in better dimensional stability. Table 4 gives the gloss measurements.…”

“…In order to address this well-known industrial problem, high temperature resistant materials were combined with low temperature curing paints. 36,37 PC/ ABS blends were one possible solution, but their high cost and relatively low chemical resistance of amorphous components limited their usage.…”

“…Many reports have shown improvements in polymer properties with the addition of ABS. [14][15][16] However, most polymers blends are immiscible and incompatible, which can generate weak interfaces and low mechanical and barrier properties. Compatibilizing agents aim to provide strong interactions between the polymer matrix and the dispersed phase.…”
