    Abstract

    Two different grades of organically modified montmorillonite were treated with several aminosilanes before compounding with a linear polypropylene (MFR=4) and a high molecular weight PP-g-MA in the same proportions in all cases. This treatment served to promote reactive coupling of the polymeric compatibilizer (PP-g-MA) to the nanolayer edges alone in some cases or to the nanolayer faces as well as edges in other cases. Edge coupling alone or coupling at the faces and edges give rise to different effects on the morphology and melt rheology -particularly strain hardening in extensional flow of the nanocomposites.
