The effects of melt intercalation processing conditons on the quality of poly(ethylene terephthalate) montmorillonite clay nanocomposites have been investigated by thermal gravametric analysis (TGA), X-ray diffraction XRD), and transmission electronic microscopy (TEM). Results show that the highest level of dispersion was achieved by melt mixing virgin PET with hexadecyl imidazolium treated MMT at 200 rpm for 2 min in a nitrogen atmosphere after drying the polymer at 120 degrees C and the clay at 150 degrees C. Alternate mixing conditions, longer residence times and higher screw speed resulted in lower quality nanocomposites.
