摘　　要：通过球磨法制备马来酸酐接枝(乙烯-辛烯)共聚物(POE-g-MAH)/有机化蒙脱土(OMMT)增韧母粒,并将其用于尼龙(PA)6的增韧改性。结果表明,球磨法制备的POE-g-MAH/OMMT增韧母粒尺寸比较均匀,有少量POE-g-MAH进入OMMT片层之间,导致OMMT片层间距有所增加。POE-g-MAH/OMMT增韧母粒在PA6基体中分布较均匀,但有轻微的团聚现象。随着POE-g-MAH/OMMT增韧母粒含量的增加,PA6/(POE-g-MAH/OMMT)共混物缺口冲击强度呈上升趋势,且当增韧母粒质量分数超过15%时,PA6/(POE-g-MAH/OMMT)共混物的力学性能优于PA6/POE-g-MAH共混物。当增韧母粒质量分数为15%、POE-g-MAH/OMMT母粒质量比为80/20时,PA6/(POE-g-MAH/OMMT)共混物缺口冲击强度和拉伸强度达到最高。POE-g-MAH/OMMT toughening particles were prepared by ball grinding method and were used to modify the toughness of PA6. The results showed that the size of POE-g-MAH/OMMT particles prepared by ball grinding method was uniform. A small amount of POE-g-MAH get into the layers of OMMT, which increased the pitch of OMMT layers. The dispersion of POE-g-MAH/ OMMT particles in PA6 matrix was better, but a slight agglomeration of particles occurred. With content of the POE-g-MAH/OMMT particles increasing, the notched impact strength of PA6/（POE-g-MAH/OMMT） blend increased. When the mass fraction of toughe- ning particle exceed 15% ,the mechanical properties of PA6/（POE-g-MAI-I/OMMT） blend were higher than PA6/POE-g-MAH blend. When the mass fraction of toughening particle was 15% and mass ratio of POE-g-MAH/OMMT was 80/20, the notched impact strength and tensile strength of PA6/（POE-g-MAH/OMMT） blend were highest.
