Different nitroxide‐terminated polystyrenes are characterized using matrix‐assisted laser desorption ionization time‐of‐flight mass spectrometry (MALDI‐TOF MS). Careful MS analysis reveals that in contrast to TEMPO‐capped chains which can be analyzed without fragmentation, a fragmentation of the N ‐oxyle group occurs in case of TIPNO and BIPNO. A fragmentation resulting in the loss of a t ‐butyl‐group is proposed as consequence of the treatment during the measurement.
