Sažetak
In our previous investigation [1] we found that the polypropylene (PP) is partially miscible with polyurethane (TPU) due to the lack of interfacial interaction between the nonpolar crystalline PP and polar TPU phases. Since PP is partially miscible with TPU the aim of this study was to investigate the compatibilizing effect of talc on the morphology, thermal and mechanical properties of TPU/PP blends. The incorporation of proper compatibilizers reduces interfacial tension, refines blends morphology and therefore leads to an improvement of processing and application properties of the final material. A series of TPU/PP blends without and with 5 wt. % of talc were prepared using a Hake Record 90 twin– screw extruder. The compatibility, thermal and mechanical properties of pure components (TPU, PP) and their blends were investigated by tensile strength test, differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). The DSC results indicated that a higher crystallization rate was obtained for TPU/PP blends when the talc is added, which can be attributed to the nucleating effect induced in PP by talc particles. The nucleating effect of the talc leads to a faster crystallization which results in an amorphous phase with a bigger mobility (lower Tg). The better compatibility between TPU and PP was obtained by talc. 1. E. Govorčin Bajsić Emi, V. Rek e- Polymers. 073 (2004) 1-10.
