Morphology and thermal behavior of TPU/PP blends modified with maleic anhydride grafted SEBS-g-MA block copolymer
The effect of the maleic anhydride grafted styrene-ethylene/butylene-styrene (SEBS-g-MA) block copolymer on the properties of thermoplastic polyurethane (TPU) and polypropylene (PP) blends were studied. Thermal properties of TPU/PP and TPU/PP/SEBS-g-MA blends with different weight ratios were prepared in twin-screw extruder and investigated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Scanning electron microscope (SEM) was used to investigate the morphological structure of obtained polymer blends as well as the effect of SEBS-g-MA block copolymer on the reduction of domain size and particle dispersion in polymer blends. The results from the uncompatibilized blends clearly indicated that the TPU and PP are immiscible resulting in undesirable properties of the blends. The thermal properties were improved when TPU/PP blends were compatibilized with SEBS- g- MA. Addition of the SEBS-g-MA block copolymers resulted in a finer dispersion of the minor phase and clearly improved interfacial adhesion.
