摘　　要：研究了K树脂的马来酸酐接枝物(K-M AH)对PA 6的干态力学性能、低温冲击性能和吸水率的影响,结果表明,K-M AH使PA 6在低温及干态条件下的冲击强度大幅度提高,而拉伸、弯曲强度变化较小。通过扫描电镜(SEM)考察了共混物的微观相态,结果显示,K-M AH在PA 6中粒径很小且分散均匀,两相界面模糊,K-M AH与PA 6相容性很好。A new toughening agent K-MAH, which was manufactured through twin-screw-extrusion machine, was used to toughen nylon6（PA6）. The influence of K-MAH of mechanical properties in dry condition, low temperature notched impact strength and ability of absorb water to PA6. The results indicated that the notched impact strength of the dry condition enhanced obviously with the increasing of K-MAH content. And when K-MAH content was 20%, the notched impact strength reached 60. 4 kJ/m^2, which was about 5.5 times of that of Pure PA6; when K-MAH content was 30%, the notched impact strength of low temperature was abottt 5.4 times of that of pure PA6. When the notched impact strength of PA6 was improved by the addition of K-MAH, the Yield strength and flexural strength changed small. The microcosmic structure of blends were studied by SEM, the results show that the compatibility of K-MAH with PA6 is well.
