Fire properties of styrenic polymer-clay nanocomposites based on an oligomerically-modified clay

An oligomerically-modified clay has been used to fabricate nanocomposites with styrenic polymers, such is polystyrene. high-impacted polystyrene, poly(styrene-co-acrylonitrile) and acrylonitrile-butadiene-styrene by melt blending, The clay dispersion was evaluated by X-ray diffraction and bright field transmission electron microscopy, All of the nanocomposites have a mixed delaminated/intercalated structure. The fire properties of nanocomposites were evaluated by cone calorimetry and the mechanical properties were also evaluated. (c) 2005 Elsevier Ltd. All rights reserved.
