摘　　要：采用纳米BaSO4及马来酸酐接枝乙烯-辛烯共聚物（POE—g—MAH）对聚酰胺（PA）6进行增韧改性，研究了PA6／POE—g—MAH共混体系的脆韧转变，讨论了纳米BaSO4的用量对PA6／POE—g-MAH脆韧转变体系的增韧作用。结果显示，当POE—g—MAH质量分数为10％～20％时，PA6／POE—g—MAH共混体系发生脆韧转变，纳米BaSO4对PA6／POE—g—MAH（85／15）脆韧转变体系的增韧效果明显，并且对材料的拉伸性能影响不大。POE-g-MAH and nano BaSO4 were used to toughen PA6, and the brittle - ductile transition of PA6/POE-g-MAH blends was studied. The toughness effects of different contents of nano BaSO4 on the PA6/POE-g-MAH blends was also discussed. Results showed that brittle-ductile transformation produced when the content of POE-g-MAH was between 10% - 20% , the notched impact strength of composites increased greatly, while the tensile strength remained.
