Vana, P., Albertin, L., Barner, L., Davis, T. P., & Barner-Kowollik, C. (2002) Reversible addition-fragmentation chain-transfer polymerization: Unambiguous end-group assignment via electrospray ionization mass spectrometry. Journal of Polymer Science, Part A: Polymer Chemistry, 40(22).

Electrospray ionization mass spectrometry was performed to identify the structure of polymeric methyl acrylates generated via the cumyl dithiobenzoate (CDB), cumyl p-fluorodithiobenzoate (CPFDB), and 1-phenylethyl dithiobenzoate (PEDB) mediated reversible addition-fragmentation chain-transfer (RAFT) polymerizations. The relatively simple spectra clearly demonstrate the end groups of this living free-radical polymerization technique. Only polymeric chains carrying one leaving group of the RAFT agent and the dithiobenzoate end group as the active RAFT center were discovered. Multiple-stage mass spectrometric experiments and oxidation of the dithioester end group confirmed the structure of the generated polymers.

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.
