The random and block co-polymers systems were studied by using ion mobility and mass spectrometry. The ion drift through the cell under the influence of a weak, uniform electric field, were mass selected with a quadrupole mass filter and detected as a function of time, yielding an arrival time distribution (ATD). The mobility of a mass-selected ion was determined from a series of ATDs measured at different electric field strength. The modeling of the copolymers show that the metal cation prefers to bond to several oxygen atoms near the end of the polymer chain away from the C 13H 27O- end.
