Reversible Deactivation Radical Polymerization in Biomass-Derived Solvents: Sustainable Approach in Polymer Chemistry

Motivated by growing concerns over the impact of conventional organic solvents on humans and their environmental safety, this review highlights recent advancements in the application of renewable resource-derived solvents in reversible deactivation radical polymerization (RDRP) techniques, with a focus on their effectiveness and potential benefits. The review begins with a concise overview of the importance of environmentally friendly solvents, outlining the specific requirements associated with their use. It then details the key parameters used to classify and evaluate solvents. Subsequently, the review examines the role and influence of solvents in various RDRP techniques, with particular attention to green solvents, especially those derived from biomass, that are gaining increasing attention in polymer synthesis. Three major classes of biomass-derived solvents are discussed: (1) lignocellulosic biomass, (2) essential oils, and (3) vegetable oils. These sustainable alternatives address both the depletion of fossil resources and environmental concerns associated with traditional solvents. The review highlights the promising outcomes achieved using these biobased solvents, demonstrating their potential to enhance the sustainability and environmental compatibility of controlled polymer synthesis.
