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。
使用環氧聚閤型擴鏈劑作為POM/ TPU共混物的相容劑，研究其對POM/TPU共混物的流變性能、力學性能、結晶性能和耐熱性的影響。結果錶明，添加環氧聚閤型擴鏈劑後，POM/TPU共混物的鎔體流動速率先升高然後降低；遲擊彊度提高，斷裂伸長率大幅提高；結晶度先升高後降低；熱變形溫度提高。

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.
