ATRP telechelic oligomers

Scheme 14 Synthesis of telechelic oligomers by chemical modification of prepolymers previously obtained by ATRP...

To the authors knowledge, most telechelic oligomers and macromonomers are obtained by ATRP. This may be explained by a relatively easy replacement of the terminal halogen atom. However, even after chemical modification, CuBr traces remain in the final product, which represents a major drawback for further industrial developments. 

In this review, the term macromer is used to describe oligomer or polymer precursors that undergo reversible association to form supramolecular polymers or networks. Macromer synthesis, although a crucial aspect of supramolecular science, is also out of the scope of this review. Several comprehensive reviews of the synthesis of H-bonding polymers are available [10, 11,42] and primarily describe the application of controlled radical polymerization techniques, including atom-transfer radical polymerization (ATRP), reversible addition-fragmentation chain transfer (RAFT) polymerization, and nitroxide-mediated polymerization (NMP). For synthesis of telechelic polymers, avoiding monofunctional impurities that can act as chain stoppers is crucially important [43],...
