Ternary blends based on polyamide 6 (PA6)/
acrylonitrile-butadiene rubber (NBR)/polycarbonate
(PC) were prepared by melt compounding via extrusion process. The effect of organoclay (OC), compatibilizer, and blend ratio was investigated on structural
and mechanical properties of the blend. The effect of
OC and compatibilizer studied on crystallization temperature, melting temperature, and crystallinity of PA6/
NBR/PC ternary blends was studied by differential scanning calorimetry. Improvement in the crystal structure
of compatibilized blend compared to unfilled blend
was observed by polarized optical microscope. Dispersion of OC into PA6/NBR/PC ternary blends was done
by X-ray diffraction, transmission electron microscopy,
and scanning electron microscopy (SEM)/energy-dispersive X-ray. The results confirmed the exfoliation of
OC particles into the polymer matrix. The improvement
in yield stress and tensile modulus of the ternary blend
was observed in the presence of OC. The impact strength
showed an increase using NBR-glycidyl methacrylategrafted (g-GMA) to prepare compatibilized PA6/NBR/PC
ternary blend.
