摘　　要：采用环氧树脂(EP)对尼龙66(PA66)进行化学扩链改性,对改性PA66的力学性能、流变行为和耐热性能进行了测试和表征。结果表明,随着EP用量的增加,改性PA66的熔体体积流动速率(MVR)降低;当EP的质量分数为4.0%时,改性PA66的缺口冲击强度、拉伸强度、弯曲强度较纯PA66分别提高了50.2%、22.0%和44.7%。PA66 was modified by the chain-extending reaction of epoxy （EP） and nylon 66 （PA66）. And the mechanical properties, rheologieal behavior and heat resistance of the modified PA66 were characterized and analyzed. The results show that with the increase in EP content, the melt volume flow rate （MVR） of the modified PA66 decreases. When the EP content is 4.0wt%, the notched impact, tensile and bending strength of the modified PA66 are improved by 50.2%, 22.0% and 44.7%, respectively, compared with pure PA66.
