A new range of selenium-based reversible addition-fragmentation chain-transfer (RAFT) agents is described and tested in the polymerization of styrene, acrylates, vinyl esters, and N-vinylcaprolactam. The synthesized N,N-dimethyldiselenocarbamates were poor control agents for styrene polymerization, ...
