Chain transfer can be performed effectively by a mechanism of addition‐fragmentation with appropriately substituted allylic compounds, vinyl ethers and thionoesters. Selection of substituents allows the optimization of chain transfer activity and the preparation of macromonomers and other end‐functional polymers from acrylates, methacrylates, styrene and vinyl acetate. The addition‐fragmentation concept has been extended to the free radical ring‐opening polymerization of cyclic allylic sulfides.
