Abstract

Thermal stability of ester-thermoplastic polyurethane (TPU)/polypropylene (PP) and ether-TPU/PP blends was evaluated by thermogravimetric studies. Thermal studies were made as a function of blend ratio. Effects of compatibilization using MA-g-PP and nanoclay addition on thermal stability were evaluated. Mass loss at 400 °C was found to decrease with increasing PP content were determined. Finally the compatibility and crystallization behavior of the blends were studied by differential scanning calorimetry. Compared to the ether-TPU blend nanocomposites, the ester-TPU blends showed better compatibility and thermal stability.
