Dynamic covalent nitroaldolpolymers of different topology is presented. Linear dynamers were generally produced, from which specific macrocycles were formed through depolymerization, driven by precipitation. The dynamers showed a clear adaptive behavior, displaying depolymerization and rearrangement of the dynamer chains in response to alternative building blocks as external stimuli.
