WebThe relative reactivityof ions and ion pairs are very different in anionic and cationic polymerizations. In anionic systems, the reactivity of ions (kp ) is similar to that of solvent-separatedion pairs (kp x), but much higher than that of contact ion pairs (kp-r) [12]. WebA commercial quadrupole/time-of-flight tandem mass spectrometer has been modified and evaluated for its performance in conducting ion/ion reaction studies involving high mass (>100 kDa) ions. Modifications include enabling the application of dipolar AC waveforms to opposing rods in three quadrupo …
