摘要
介绍聚甲醛(POM)的热分解特征、热稳定性评价方法及各种添加剂对POM的热稳定化作用,讨论了位阻酚类抗氧剂和位阻胺类光稳定剂并用,以及添加含双键化合物或聚酰胺低聚物等改善POM热稳定性的方法。
The thermodecomposition characteristics and the evaluation methods of thermostability for POM and the thermostabilizing effects on polyacetal by all kinds of additives are introduced. Several means were discussed to improve the thermostability of polyacetal by using hindered phenolic antioxidant, hindered amine light stabilizer or adding pounds with double linkages or polyamide oligomers.
