Abstract
The tensile and fatigue properties of styrene-based rubber modified polymer blends and its PC blends were inventigated and their morphology and profile of fracture surface were observed using by TEM and SEM. It is concluded as follows: the ductility of the polymer blends were improved by PC added. The fatigue crack properties of all polymer blends were dominated by Paris rules. Their Young's modulus and the reduction of area decreased with the increase of diameter of rubber particle. There are no correlation between the properties of tensile and fatigue in all the polymer blends. The fatigue crack propagations of the polymer blends having the island-sea structure were affected by their morphology than materials of island structure. The extension of sea structure along with the orientation of crack propagation made the resistance of crack propagation weak. Furthermore, the increase of ligament in sea tends to make the increase of crack propagation resistance.
