| 摘 要： | 研究了在主抗氧剂Ｉｒｇａｎｏｘ２４５存在下，聚酰胺（ＰＡＴ）和双氰胺（ＣＧ）稳定共聚甲醛（ＰＯＭ）的效果。研究表明ＰＡＴ与ＣＧ并用有较好的协同作用，当Ｉｒｇａｎｏｘ２４５用量为０５％、ＣＧ０３％、ＰＡＴ０１％时可达到最佳的稳定化结果，在２２０℃下加热１ｈ共聚甲醛的热失重率仅为０３６５％

| Abstract: | The heat stability of POM was improved
by using polyamide (PAT) and cyanoguanidine(CG),with Irganox 245 as main antioxidant.The
results showed when PAT and CG were both used,there was a synergistic action for the
stabilization of POM.When Irganox 245 content was 0.5%,CG 0.3% and PAT 0.1%,the
stability was the best,resulting in a weight loss ratio of 0.365% at 220 for 1h. |
