摘　　要：采用熔融共混反应挤出法制备N,N,N′,N′-四缩水甘油基-4,4′-二氨基二苯甲烷(TGDDM)反应增容的聚苯醚(PPO)/聚酰胺66(PA66)合金。采用傅里叶红外光谱法对反应产物的结构进行了研究,并对共混物的流变性能、力学性能、微观结构进行了分析。结果表明,反应挤出过程中生成了起相容作用的PA66-co-TGDDM-co-PPO;随着TGDDM含量的增加,合金体系的熔体流动速率降低,能耗增大;少量的TGDDM即可明显改善合金体系的力学性能;TGDDM能使分散相粒子的形状发生变化。Polystyrene oxide （PPO）/polyamide 66 （PA66） alloys containing a reactive compatibilizer, N, N, N＇, N＇-tetraglycidyl-4, 4＇-diamqnodiphenyl methane （TGDDM）, were prepared via melting reactive extrusion. The structure of the alloys was studied using Fourier transform infrared spectroscopy. The mechanical properties, rheological behavior, and microstructure of the obtained blends were investigated. It showed that, PA66-co-TGDDM-co-PPO copolymers were formed in the reactive extrusion. With increasing amounts of TGDDM, melt flow rates of the alloys decreased, and energy consumption increased. A drastic improvement of mechanical property was observed upon addition of a very small amount of TGDDM. Scanning electron microscope showed that TGDDM changed the shape of the dispersed phase particles.
