【摘要】 聚甲醛(POM)因具有优异的耐磨性、耐疲劳、耐蠕变性、耐化学药品性等特性，被广泛应用于制作尺寸要求精密的汽车和电子电器等工业部门。然而聚甲醛的热稳定性、耐候性、抗老化性、耐紫外光以及阻燃性等性能差，这大大限制了POM在诸多领域中的应用。因此通过合金化、复合化对聚甲醛进行改性研究，改善材料性能具有极其重要的意义。更多还原

【Abstract】 Polyformaldehyde(POM)was widely used in the production of precise size requirements of automotive and electronic and electrical industries due to its excellent wear resistance, fatigue resistance, creep resistance, chemical resistance and other properties.However, POM had poor thermal stability, weather resistance, aging resistance, ultraviolet(UV)resistance and flame retardancy, which greatly limited the application of POM in many fields.Therefore, it was significant to improve its properties by alloying and compounding.更多还原
