| 摘 要： | 用双螺杆挤出机制备了(甲基丙烯酸甲酯/丁二烯/苯乙烯)共聚物(MBS树脂)与尼龙6(PA6)的共混物。使用扫描电镜(SEM)、熔体流动速率(MFR)和力学性能测试等分析方法,研究了马来酸酐(MAH)熔融接枝MBS(MBS-g-MAH)对PA6/MBS共混物的形态结构和力学性能等的影响。结果表明,MBS-g-MAH中的酸酐基团与PA6末端的氨基发生化学反应,原位形成的MBS-PA6共聚物,能有效地改善PA6与MBS的相容性,可以使MBS均匀地分散在PA6基体中,相区尺寸明显减小。PA6/MBS-g-MAH(70/30)体系冲击强度、拉伸强度、弯曲强度分别比PA6/MBS(70/30)提高了319%、54%、35%,从而得到综合性能优良的共混合金。

| Abstract: | The melt grafting of maleic anhydride(MAH) onto(2-methyl methacrylate-1,3-butadiene-styrene)terpolymer(MBS resins) was used to prepare compatibilizer(MBS-g-MAH),and its effects on nylon 6(PA6)/MBS blends were studied by the scanning electron microscope(SEM),the melt flow rate(MFR)and mechanical testing methods.The results show that the anhydride group in MBS-g-MAH reacts with the amine end groups of the PA6,and MBS-PA6 copolymers are formed in situ,which effectively improves the compatibility between MBS an... |
