Radiation Degradation and Stability of Polymer

In recent years, because of the advantage of radiation technology-low energy, clean, environmental protection, etc., so that the use of radiation technology for polymer synthesis or processing research continues to heat up; however polymer materials irradiated via high-energy radiation prone to produce free group or to react with atomic oxygen in the air, resulting in the material cracking, crosslinking, branch, etc., it affects the performance of the materials. In this paper, we focus on the need for the research of radiation resistance of polymer material, It highlights the basic mechanism of polymer materials irradiation discoloration and the formulation of radiation resistant materials, which includes plasticizers, stabilizers, antioxidants and light stabilizers, the most representative is the study of a hindered amine light stabilizer and the latest irradiated materials research.
