Sažetak
Neat thermoplastic polyurethane (TPU), polypropylene (PP) and TPU/PP blends with different weight ratios prepared in a twin-screw extruder were investigated by differential scanning calorimetry (DSC), light and scanning electron microscopy. The results confirmed PP matrix → TPU matrix phase inversion in the concentration region between TPU/PP 60/40 and 80/20 blends. Total degree of crystallinity of the blends and the crystallization temperature of the PP decreased with increasing TPU content. On the other side, the addition of elastomeric TPU to the PP significantly increased the spherulite size of polypropylene. The TPU melt islands in the PP matrix prolonged the crystallization of the PP during solidification process enhancing thus the growth of spherulites.
