Abstract: Acrylonitrile-butadiene-styrene (ABS)/montmorillonite nanocomposites have been prepared using a direct melt intercalation technique by blending ABS and organophilic clay of two different particle sizes: OMTa (5 mum) and OMTh (38 mum). Their structure and flammability properties were characterized by X-ray diffraction, high resolution electronic microscopy (HREM), thermogravimetric analysis (TGA) and cone calorimeter experiments. The results of HREM showed that ABS/5 wt% OMTa nanocomposite was a kind of intercalated-delaminated structure, while ABS/5 wt% OMTh nanocomposite was mainly an intercalated structure. The nanocomposites showed a lower heat release rate peak and higher thermal stability than the original ABS by TGA and cone calorimeter experiments. Also, the intercalated nanocomposite was more effective than an exfoliated-intercalated nanocomposite in fire retardancy. (C) 2003 Society of Chemical Industry.
