摘要：

Considering the limitations of the current technology used to prepare polyolefin/clay nanocomposites, this work deals with new approach involving the use of block copolymers to enhance the affinity between montmorillonite and low polarity polymeric matrices. In this approach sodium montmorillonite slurry is directly modified using an amphiphilic diblock copolymer which has a reactive block capable of reacting with montmorillonite and a low polarity block that has affinity towards low polarity polymeric matrices. X-Ray diffraction and thermogravimetric analyses show complete exfoliation and better thermal properties compared to commercially available organoclays.
