Abstract:
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.

As shown below, the mechanism involves a nucleophilic attack by water at the carbonyl carbon to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen π bond along with the departure of a halide ion. A final proton transfer step yields carboxylic...
