Polypropylene-clay (montmorillonite) nanocomposites were prepared by melt compounding. The impact properties were modified by reactively bonding oligomeric, end functionalized elastomer to the polymeric chains. For comparison purposes, another sample was prepared where end functionalized polyolefin elastomer was also reactively bonded to the polymeric chains of the nanocomposites. Based on stress-strain curves and impact testing we have found improvement in the impact properties of the nanocomposites containing the oligomeric elastomer, compared with that containing polyolefin elastomer, without sacrificing the tensile properties. This was supported using TEM, DSC and XRD.
