Interpretive Summary: Deep eutectic solvents (DESs) are relatively new, but they have already found many applications in organic, analytical, and polymer chemistry. The recent discovery of natural deep eutectic solvents (NADES), where many plant-abundant primary metabolites were found to change their state from solid to liquid at certain temperatures when mixed in a proper ratio, should accelerate their use as replacements for common organic solvents that exhibit inherent toxicity and high volatility. In this work, the use of NADES for polymerization and polymer reactions is reviewed. In view of NADES as an agro-based and environmentally friendly reaction media, we believe they have great promise as green solvents for polymer research and development.

Technical Abstract: Green chemistry is a key opportunity in chemistry and chemical engineering today because it can potentially preserve the environment and human health. It entails the choice of natural biodegradable raw materials and solvents, environmentally acceptable processes, and minimal use of non-hazardous chemicals. Previously, deep eutectic solvents (DES) have found many applications in organic, analytical, and polymer chemistry. The recent discovery of natural deep eutectic solvents (NADES), where many plant-abundant primary metabolites have been found to change their state from solid to liquid at certain temperatures when mixed in a proper ratio, should accelerate their use as replacements for common organic solvents that exhibit inherent toxicity and high volatility. In this work, we have reviewed the application of NADES as green, sustainable solvents in processes that involve polymerizations and polymer reactions. It is clear that many applications have already been explored. Undoubtedly more progress will be made in the future, and NADES will become more commonly used in polymer-related processes.
