摘　　要：使用环氧聚合型扩链剂作为POM/TPU共混物的相容剂,研究其对POM/TPU共混物的流变性能、力学性能、结晶性能和耐热性的影响。结果表明,添加环氧聚合型扩链剂后,POM/TPU共混物的熔体流动速率先升高然后降低;冲击强度提高,断裂伸长率大幅提高;结晶度先升高后降低;热变形温度提高。Using epoxy polymer chain extender as POM/TPU blends’compatibility agent,the effect on the rheological properties,mechanical properties,crystallization properties and heat resistance of POM/TPU blends were studied. Results show that the addition of epoxy polymer chain extender POM/TPU blends melt flow rate first is increased and then reduced;impact strength is improved,elongation at break is increased;crystallinity degree is first increased than lowered;heat distortion temperature is increased.
