Abstract

The control over the chain-end functionality of a polymeric chain produced by controlled/‘living’ radical polymerization is inherent to the mechanism of the re- action. Indeed, the final product contains a majority of polymeric chains showing an ω-functional end group which is used to control the molecular weight growth. The growth of the molecular weight can be mediated either via the reversible homolytic cleavage of the covalent bond between the terminal carbon and the chain-end group (e.g. halogen for transition-metal-mediated living radical poly- merization/atom transfer radical polymerization (ATRP), nitroxide for nitroxide- mediated polymerization (NMP)) or via the degenerative transfer of chain-end groups between propagating radicals and dormant species (e.g. thiocarbonylthio groups for reversible addition–fragmentation chain transfer (RAFT)). Furthermore, α-functional end groups can also be introduced via the initiator/mediator of the polymerization, for example, halogen alkyls (ATRP), alkyl nitroxides (NMP) or dithioesters (RAFT)...

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
