| Abstract: | 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 rheological properties were studied by using TGA and capillary rheometer,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. |
