Thermogravimetric analysis organoclays

The thermal stability of the nanocomposites polybutyleneterephtalate, briefly PBT, (or polyethyleleteiephtalate)/organoclay determined by the thermogravimetric analysis is presented in Table 3 and in Figures 14 and 15 [11,12].

In this work, alkyl pyridinium, itnidazolium and phosphonium cationic surfactants were used to produce highly thermally stable organoclays. The volatile products issued from the thermal decomposition of those organoclays were analyzed by mass spectroscopy (MS). The organoelays were compounded with LLDPE and an appropriate compatibilizer. The micro- and nanodispersions were investigated through X-ray diffraction (XRD) and electron microscopy (SEM, TEM). The thermal stability of the nanocomposites was evaluated by thermogravimetric analysis (TGA).
