Based on the mechanism of catalyst deactivation at high temperature, the effect of accelerated aging method on deactivation was studied.
基于催化剂高温失活机理，分析了不同快速老化方法对催化剂劣化强度的影响。
The stabilizing agent made the melting process steady because it held back cross-linking and aging of PVA at high temperature.
稳定剂的添加，可明显改善PVA的熔融加工稳定性，使其交联老化程度降低，薄膜的溶解性能显著提高；
