摘　　要：用双螺杆挤出机制备了三氧化二锑 /聚丙烯 (Sb2 O3/PP)和丙烯酸 (AA )改性Sb2 O3/PP母料 ,用IR、熔体流动速率仪和SEM研究了Sb2 O3/PP母料和改性Sb2 O3/PP母料中化学作用、熔体流动速率和断裂形态。结果表明 ,AA在母料中能与Sb2 O3 发生强的界面相互作用 ,与PP发生接枝作用 ,使母料的熔体流动速率降低 ,改善粒子与基体的界面粘结 。The Sb 2 O 3 /PP masterbatch and Sb 2 O 3 /PP masterbatch modified by acrylic acid (AA) with or without DCP were prepared by using a twin-screw extruder. The chemical interaction, melt flow rate and fracture morphologies of Sb 2 O 3 /PP masterbatch and modified Sb 2 O 3 /PP masterbatch were investigated by IR and SEM. The results indicated that the addition of AA decreased the melt flow rate. The absorb peak of 1 715cm -1 was observed by IR. It was attributed that the chemical interactions among the components exist. The interfacial interaction improved the interfacial adhesion and changed the fracture morphologies of Sb 2 O 3 /PP masterbatch.
