摘要: A systematic investigation on the effects of type compatibilizer precursors (CP) upon barrier properties and morphology PE/PA blends was reported. Three alkyl carboxyl-substituted polyolefins were selected to modify PA in a twin screw extruder by “reactive extrusion” process. The property modified (MPA) better than pure PA, amount improvement blend PE MPA dependended significantly prepared. extent mixing before blow-molding has significant effect its corresponding properties. Further analysis fracture surfaces indicated that more demarcated laminar structure dispersed matrix is essential for PE/MPA blends. It not completely clear how CP added affects MPAs. However, it suggested long sequence with shorter grafted chain high normalized grafting efficiency are preparing MPA, good
