Research Progress of Polyurethane Containing Reversible Bonds
A type of polyurethane with reversible bonds in its molecular chain was called polyurethane containing reversible bonds.Under certain conditions,the reversible bonds would be broken,and polyurethane was granted new structures and properties.When the conditions were removed,the original structures and qualities of the polyurethane would be reverted,and this transformation could be repeated.In this paper,the current major synthetic routes and performance characteristics of polyurethane containing reversible bonds was reviewed,the research progress of polyurethane containing reversible non-covalent bonds and reversible covalent bonds structures was summarized,the application of polyurethane containing reversible bonds was prospected.
