Impact modified blends of polypropylene (PP) and a commercial polyolefinic elastomer (POE) were prepared and further reinforced with suitable nanoclay. The addition of elastomer and nanoclay improved the impact properties significantly, whereas moderate improvement was observed in tensile strength, flexural strength, flexural modulus, and elongation at break. The heat distortion temperatures of the filled compositions were close to that of neat PP. The compositions exhibited excellent flow characteristics. Blending sequence between PP, POE and Nanoclay was altered and its effect on the properties of Nanocomposite was investigated. The preferential migration of the blend components leading to different intercalated morphology was reported.
