Biochemical systems make use of out-of-equilibrium polymers generated under kinetic control. Inspired by these systems, many abiotic supramolecular driven chemical fuel reactions have been reported. Conversely, based on transient covalent bonds received little attention, even though they the potential to complement generating structures stronger and offering a straightforward tuning reaction kinetics. In this study, we show that simple aqueous dicarboxylic acids give poly(anhydrides) when treated with carbodiimide EDC. Transient molecular weights exceeding 15,000 are which then decompose over course days. Disassembly kinetics can be controlled using substituent effects in monomer design. The impact solvent polarity, concentration, concentration polymer properties lifetimes has investigated. results reveal substantial control assembly disassembly kinetics, highlighting for fine-tuned nonequilibrium polymerization systems.
