A series of nanocomposites based on polystyrene (PS) and organophilic layered silicates (OLS) were prepared by solution blending method using organophilically modified silicate with ammonium salt of poly(styrene‐ran‐(4‐vinylbenzyl chloride)). Two different types of base layered silicate were used for the preparation of the nanocomposites: sodium montmorillonite (Na‐MMT) and synthetic smectite (SWN). The morphology and thermal stability of the PS/OLS nanocomposites were characterized by TEM and TGA. The rheological properties of the nanocomposites were investigated using a stress‐controlled rotational rheometer under small amplitude oscillation and steady transient shear in their melt state. In addition, the effects of the contents and aspect ratio of OLS on the melt rheological properties were investigated.
