Abstract
AbstractIn recent years, the fully oxygen‐tolerant reversible deactivation radical polymerization (RDRP) has become a highly researched area. In this contribution, a new and minimalist method is successfully employed to accomplish fully oxygen‐tolerant reversible addition‐fragmentation chain transfer (RAFT) polymerization using bis(trithiocarbonate) disulfides (BisTTC) as an iniferter agent, where the released sulfur‐centered trithiocarbonate (TTC) radical can initiate monomer. Furthermore, polymerization kinetics revealed the typical “living” features of this polymerization system. More importantly, by high‐throughput screening, it is found that dodecyl‐substituted TTC is responsible for the fully oxygen‐tolerant RAFT polymerization though trithiocarbonate radical initiation and R radical deoxygenation. It is believed that trithiocarbonate radical initiation strategy provides a powerful and minimalist tool for fully oxygen‐tolerant RDRPs.
