Description

technical field

[0001] The invention belongs to the technical field of organic degradation, and in particular relates to a precise degradation method of polyalkyne ester compounds. Background technique

[0002] Man-made polymers such as plastics, rubber and fibers are widely used nowadays, but when they are discarded, they have caused more and more serious impact on the environment due to their non-degradable characteristics. Therefore, it is of great significance to develop degradation methods for polymer materials.

[0003] At present, a variety of degradable polymer materials have been synthesized. Most of them have unknown structures after degradation, and it is difficult to recycle them again, which is not in line with the concept of sustainable development. Therefore, the development of precise degradation of polymers and the recyclability of degradation products are current research hotspots. Li Zichen et al. (Lv A., Cui Y., Du F.S., etal. Thermally degradable polye...
