Abstract

Polypropylene/clay nanocomposites were prepared by using a two step melt compounding process on twin screw extruders. The PP-clay nanocomposites were Theologically investigated. The melt rheological measurements were performed using an ARES-rheometer in the dynamic mode at 220°C over frequency varying from 100 to 0.017 rad/s and in the parallel plate geometry with 25 mm diameter. The results showed that the storage modulus and viscosity are found to be increased with the incorporation of clay into PP. The values of storage modulus and viscosity are significantly increased by the incorporation of modified clay and their rheological behavior changed completely. The results of samples with modified clay showed an evidence of the exfoliation which could be detected Theologically.
