摘　　要：将乙烯–辛烯共聚物接枝马来酸酐(POE-g-MAH)和乙烯–辛烯共聚物接枝甲基丙烯酸缩水甘油酯(POEg-GMA)复配作为增容剂,采用熔融共混的方法制备尼龙(PA)6/聚对苯二甲酸丁二酯(PBT)合金。通过扫描电子显微镜、力学性能和吸湿性研究了PA6/PBT配比和增容剂用量对合金性能的影响。研究表明,增容剂的加入能改善PA6/PBT合金的相容性,PBT和增容剂的加入能有效地抑制PA6的吸水率。添加15份增容剂可使合金的缺口冲击强度达到15.5 k J/m^2,相比未加入增容剂提高385.9%。Polyamide(PA)6/poly(tetramethylene terephthalate(PBT)alloy was prepared with ethylene-octene copolymergrafted by maleic anhydride(POE-g-MAH)and ethylene-octene copolymer grafted by glycidyl methacrylate(POE-g-GMA)ascompatibilizer through melt-blending.The effects of PA6/PBT ratio and compatibilizer content on the properties of PA6/PBT alloywere studied by scanning electron microscopy,mechanical properties and hygroscopic properties tests.The results show that thecompatibilizer can improve the compatibility of PA6/PBT alloy.The addition of PBT and compatibilizer can effectively inhibit thewater absorption of PA6.When compatibilizer content reaches15phr,the Izod notched impact strength of alloy is15.5kJ/m2andincreases by385.9%compared with that without compatibilizer.
