| Popis: |
The styrene-ethylene/butylene-styrene/polystyrene (SEBS/PS) blends were prepared by melt blending. The mechanical properties of PS/SEBS blends were influenced by the increase of SEBS contents. When the content of SEBS increased to 13 wt%, the impact strength of SEBS/PS blends boosted the maximum value. Young’s modulus and tensile strength of SEBS/PS blends decreased with the increase of SEBS. The fracture surfaces obtained during Izod impact resistance tests were obtained by scanning electron microscopy (SEM). The results indicated that the number of particles of SEBS dispersed in PS matrix. The diameters of particles of SEBS were about 1.5-3 µm. SEBS/PS blends absorbed more energy than pure PS during impact resistance tests. |
