【Abstract】 A new method is researched for the preparation of the rigid-particle toughening and reinforcing polymer composites with core/shell dispersed phase structure. Commonly, core-shell structured phase is obtained through solution encapsulation, emulsion encapsulation, reactive extrusion and so on. However, these methods are hard to be applied in industry because of complexity of the prepared procedure. In order to find a way to obtain the core-shell structured polymer composite for industry processing, a method for preparing master batch from rubber (20 %) , filler (80%) and additives by twin screw extmder was proposed. Based on the technique of master batch filled polymer, the polymer composite with high toughness and high modulus was obtained during melt processing. Meanwhile, the master batch filled polymer composites have good processing properties.更多还原
