摘要
利用TG-DTG-DTA方法研究了尼龙610在N2和空气气氛中以不同升温速率β时的热降解过程和动力学,实验发现,尼龙610在空气中的热降解过程为两步反应,在N2中为一步反应;随着β的增加,其降解温度线性升高。在N2气氛中的降解率和热降解温度均比空气中高,结合反应热效应,探讨了反应机理。
The melting behaviours of the nascent state and the second state of PA1010/6 copolymers are studied by means of DSC It is found that the high melting temperature( T 1) and the low melting temperature ( T 2) of the nascent state are different dependences on the compositions, and the second states have cold crystallization Relations of the temperature (T c) and the time (t c) of the cold crystallization between the composition is discussed
