Electron Capture Dissociation of Trithiocarbonate-Terminated Acrylamide Homo- And Copolymers: A Terminus-Directed Mechanism?. Morgan, T., Kerr, A., Wootton, C., Barrow, M., Bristow, A., Perrier, S., & O'connor, P. Analytical Chemistry, 2020. doi abstract bibtex Copyright © 2020 American Chemical Society. The structure and sequence elucidation of complex homo- and copolymers is key for further understanding polymers, polymer synthesis, and polymer interactions in biological processes. In this contribution, poly(dimethylacrylamide) homo- and dimethylacrylamide/4-acryloylmorpholine block copolymers were synthesized and analyzed by electron capture dissociation (ECD) and Fourier transform ion cyclotron resonance (FT-ICR) tandem mass spectrometry. Double-resonance experiments were carried out, providing a better understanding of the fragmentation process. A novel radical dissociation process is presented, and electron capture caused a specific cleavage at the terminal butyl-trithiocarbonate group, which initiated a free radical dissociation process.
