Abstract
We survey progress in the development of the processes for radical-promoted single-unit monomer insertion (SUMI) or reversible deactivation radical addition (RDRA), focussing on aminoxyl- [nitroxide-] mediated SUMI (NM-SUMI), reversible-addition-fragmentation chain transfer-SUMI (RAFT-SUMI) and atom-transfer radical addition (ATRA). Radical-promoted thiol-ene processes are also briefly discussed. We detail the strategies for achieving selectivity with respect to single unit insertion vs oligomerization and look critically at progress towards discrete oligomer synthesis by consecutive SUMI reactions. We examine the use of SUMI to install α-, ω- or mid-chain-functionality in RDRP-synthesized polymers. Finally, we examine the prospects for using radical-promoted SUMI in the synthesis of sequence-defined polymers where monomer placement is precisely defined to the level of the individual monomer units in the polymer chain.
期刊介绍：
Progress in Polymer Science is a journal that publishes state-of-the-art overview articles in the field of polymer science and engineering. These articles are written by internationally recognized authorities in the discipline, making it a valuable resource for staying up-to-date with the latest developments in this rapidly growing field.
The journal serves as a link between original articles, innovations published in patents, and the most current knowledge of technology. It covers a wide range of topics within the traditional fields of polymer science, including chemistry, physics, and engineering involving polymers. Additionally, it explores interdisciplinary developing fields such as functional and specialty polymers, biomaterials, polymers in drug delivery, polymers in electronic applications, composites, conducting polymers, liquid crystalline materials, and the interphases between polymers and ceramics. The journal also highlights new fabrication techniques that are making significant contributions to the field.
The subject areas covered by Progress in Polymer Science include biomaterials, materials chemistry, organic chemistry, polymers and plastics, surfaces, coatings and films, and nanotechnology. The journal is indexed and abstracted in various databases, including Materials Science Citation Index, Chemical Abstracts, Engineering Index, Current Contents, FIZ Karlsruhe, Scopus, and INSPEC.
