Influence of compatibilizer type, polypropylene molecular weigth and blending sequence

on montmorillonite exfoliation in nanocomposites (in English)

Polimery 2004, No 1, 52


Summary

Montmorillonite exfoliation in polymer matrix is a crucial factor for obtaining a material with improved barrier properties, reduced flammability, higher elastic modulus and tensile strength. One of the ways to obtain polypropylene based nanocomposite with montmorillonite involves an application of compatibilizers, for example maleic anhydride or acrylic acid grafted polypropylene. The effects of blending sequence, polypropylene molecular weight, and properties of a compatibilizer on exfoliation of montmorillonite were studied.
