通过扫描电镜、热分析、熔体流动速率和力学性能等测试方法研究了马来酸酐(MAH)和苯乙烯(St)多单体熔融接枝VERSIFY2300(V-2300-g-(MAH-co-St))对PA6/MBS/PP共混物的结晶行为、相形态和力学性能的影响.结果表明,在熔融共混过程中.V-2300-g-(MAH-co-St)中的酸酐基团与PA6的端氨基原位生成的接枝共聚物有效降低了共混物的界面张力,接枝物中苯乙烯基团与甲基丙烯酸甲酯(M)-丁二烯(B)-苯乙烯(S)三元共聚物(MBS)作用,有助于提高共混物的相容性.当PA6/MBS/PP共混物加入V-300-g-(MAH-co-St)质量分数为20%时,共混物分散相的尺寸明显减小,力学性能得到较大提高.
