Innovative Poly(Butylene Terephthalate) Based Nanocomposites: a Preliminary Investigation

A polymer‐clay nanocomposite based on Poly(butyleneterephthalate) (PBT) and an innovative organoclay has been synthesized via intercalation of Bis(hydroxyethyl terephthalate) (BHET) in Na‐Montmorillonite layers. Chemical and physical properties of this nanocomposite have been studied in comparison t...

Description
Summary:A polymer‐clay nanocomposite based on Poly(butyleneterephthalate) (PBT) and an innovative organoclay has been synthesized via intercalation of Bis(hydroxyethyl terephthalate) (BHET) in Na‐Montmorillonite layers. Chemical and physical properties of this nanocomposite have been studied in comparison to other PBT/nanocomposites based on two commercial organoclay: Cloisite 25A and Somasif MEE. Nanocomposites have been prepared via melt compounding using a twin‐screw extruder, with extrusion rate of 150 rpm. Samples were characterized by using wide‐angle X‐ray diffraction, TEM, thermal and mechanical analysis.
