摘要
主要利用多种检测技术,分析了高聚物F2314在特定的加速湿热老化条件下的相关性能变化,实验结果表明:F2314不同组份之间发生了形变和迁移,含氟基团有向表面高温区迁移的空间趋向;并且其分子量下降,结晶度增高;分子式中的不稳定结构,随着温度的升高,含量减少。
The change of F2314 performance in a accelerated ageing system is presented by various analyzing methods. Analyzing and discussing from the experimental result, we got the change trend： the deformation and migration occurred in the different component parts, and those groups which contain F element moved to the higher temperature area. Its molecular weight was depressed and labile structure were reduced with the temperature rising.
