제목 | Properties of Polypropylene/Thermoplastic Polyester Elastomer Blends and Effects of a Compatibilizer |
초록 | Polypropylene (PP) is one of the important and common thermoplastics. The modification of PP for engineering applications has attracted attention in both academic and commercial fields. Thermoplastic polyester elastomer (TPEE) offer superior mechanical properties, heat resistance, flexibility and chemical resistance, elasticity, which allow it to be widely used for electronic instruments, automotive parts. Herein, PP is improved by means of blending it with TPEE. However, most polymers are not immiscible with each another in blending situations. Blending immiscible polymers usually results in a multiphase blend. Interfaces between multiphase have negative effects on determining mechanical properties of these blends. This problem can be resolved by using proper compatibilizers. As a special additive, compatibilizers usually concentrate at interfaces during blending and play the roles of reducing interfacial tension, preventing coalescence and strengthening interface adhesion. As a result, it gives a pair of immiscible polymers compatibility. Herein, a maleic anhydride-grafted-polypropylene (MA-g-PP) was utilized to compatibilize PP/TPEE blends. The resulting blends were characterized by means of universal testing machine (UTM), scanning electron microscopy (SEM), differential scanning calorimetry (DSC). Effects of the compatibilizer for PP/TPEE blends can be confirmed with morphology by SEM. In SEM image, MAPP was effective in strengthening PP/TPEE interface adhesion. Thermal and mechanical properties of PP/TPEE blends is investigating. |
