Isotactic Polypropylene (iPP) based nanocomposites filled with organo‐clay nanoparticles were prepared and the relationships between their structure and properties were investigated. Modified C 16 ‐C 18 smectite clay nanoparticles were used in order to promote matrix/filler compatibilization and to improve interfacial adhesion. X‐Ray analysis performed on the nanocomposites demonstrated that at low organo‐clay content (1 and 3% by weight) a nanostructure has been obtained, while in presence of 5% by weight of organoclay cluster regions have been formed. Mechanical tests showed that the elastic modulus increases of about 20% compared to the neat polymeric matrix value when 1 and 3% of nanofiller is added.
