Synthesis of Polymers Containing Vicinal Tricarbonyl Moiety and Construction of Reversible Crosslinking-decrosslinking Polymer System

Abstract

Vicinal tricarbonyl compounds, chemical species having three contiguous carbonyl groups, readily react with various nucleophiles, such as water, alcohols, thiols, and aromatic amines without any catalyst, and moreover, these addition reactions are reversible under appropriate conditions. Therefore, reversible crosslinking－decrosslinking systems can be constructed by incorporating vicinal tricarbonyl structures into polymers. This review deals with the network formation based on the reaction of vicinal tricarbonyl compound and polymer recycling by means of decrosslinking of the networked polymers.
