Research Abstract |
We developed facile synthesis of degradable polyperoxides by the radical alternative copolymerization of 1,3-diene monomer with molecular oxygen at atmospheric pressure. We revealed copolymerization mechanism, degradation behavior, the synthesis of functional polyperoxides, and the application of functional polyperoxides. Degradation of polyperoxides occurred by various stimuli such as heating, UV irradiation, redox reaction by amines, and enzyme reaction. Various functional polyperoxides were synthesized by two methods, i.e., the direct copolymerization of functional 1,3-diene monomers with oxygen and the functionalization of precursor polyperoxides. Water soluble polyperoxides reversibly showed LCST under degradation temperature. Versatile methods to introduce dienyl groups into precursor polymers were developed. The resulting dienyl-functionalized polymers were utilized to prepare degradable networked polymers with small heat evolution during degradation and degradable branched copolymers to study their microphase-separated structure change before and after degradation. The practical application of polyperoxides were also investigated.
