| Summary: | Electrospray ionization time‐of‐flight mass spectrometry (ESI‐ToF‐MS) has been successfully employed for the characterization of molecular weight, molecular weight distribution and end groups for bromine‐terminated perfluoroalkyl acrylate oligomers prepared using atom transfer radical polymerization. Intact oligomers and smaller quantities of common side products were observed from m/z 1000 to 4000 cationized with a sodium ion, a difluorobenzyl cation or a proton with a minimum of multiply charged species. Number average molecular weight and weight average molecular weight for both the samples that were characterized were in reasonable agreement with independent measurements conducted using GPC‐MALS and 1H NMR spectroscopy.
