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.
