High-impact polystyrene (HIPS)/organomontmorillonite (Org-MMT) nanocomposites and HIPS/inorganic montmorillonite (MMT) conventional composites were prepared by melt processing using a twin-screw extruder.Their thermal and theological properties were studied by using TGA and capillary theometer
respectively.The differences in properties between the two types of composites were examined.The results show that the nanocomposite has better thermal stability and flowing properties than pristine HIPS or the conventional composite
and the former has a more outstanding shear-thinning behavior.In addition
when the montmorillonite is dispersed in nanoscale
the surface quality of the composites is improved evidently.
