Abstract Taking PA66 as matrix resin and maleic anhydride grafted polyolefin elastomer POE-g-MAH as toughening
， ，
agent the composites with different contents of toughening agent were prepared by melt extrusion and their micro mor-
， ，
phology flow properties mechanical properties and molding shrinkage were tested and characterized． Atomic force mi-
� �
croscopy AFM shows that POE-g-MAH is uniformly dispersed in PA66． The melt index and flow properties of the com-
posite decrease because of the reactive compatibilization of the two components． The mechanical properties test shows
，
that POE-g-MAH can significantly improve the impact properties of PA66 composites and the tensile strength and flex-
ural strength of the composites gradually decrease with the increase of POE-g-MAH c
