Reversible Deactivation Radical Polymerization in Heterogeneous Systems: Enhancing Access to High Molecular Weight Polymers

High molecular weight (HMW) polymers (M_n > 500 kg mol^–1) are indispensable in advanced applications owing to their superior physical properties and performance characteristics. While homogeneous reversible deactivation radical polymerization (RDRP) systems struggle with viscosity-driven limitations at high conversions, heterogeneous RDRP techniques (emulsion, miniemulsion, dispersion) offer compelling environmental, kinetic, and processing advantages. This Perspective examines the synthesis of HMW polymers in these heterogeneous systems, highlighting their unique mechanistic features, rapid kinetics, and scalability. We also outline the challenges and opportunities in system engineering, polymer chain engineering, polymerization techniques, and circularity. By bridging fundamental insights with industrial scalability, heterogeneous RDRP systems stand at the forefront of macromolecular innovation for next-generation materials that harmonize performance with sustainability.

期刊介绍： Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
