摘要:由均聚和共聚甲醛在氮气和空气中的热重分析曲线,探讨了聚甲醛的链结构和聚甲醛的各种降解方式同热失重的关系,并利用Coats-Redfern方法计算了共聚甲醛在空气中的动力学参数,对聚甲醛的热稳定性作了讨论.
he thermogravimetric analysis (TGA) of polyoxymethylene (POM) homopolymer and copolymer was investigated both in nitrogen and air atmosphere. It is founcthat the thermogravimetric behavior was related to the mainchain structure and degradation types of POM. The kinetic parameters of POM degradation in air was correlated by Coats-Redfern's method in this paper and the thermostability of POM wasdiscussed as well.
