MALDI-TOF Mass Spectral Characterization of Covalently-Cationized Polystyrene
Sheng Lin-Gibson, S Bencherif, Kathryn Beers, H M. Byrd
Bromine terminated, controlled molecular mass polystyrene with narrow polydispersity (Mn 40 000 g/mol, PD = 1.08) was prepared by atom transfer radical polymerization. The bromine end group was subsequently substituted with a phosphonium salt. We report the highest molecular mass polymer detected to date by MALDI analysis using chain-end functionalization for ionization. A similar molecular mass and molecular mass distribution determined by MALDI analysis was observed for Br-terminated polymer ionized using traditional metal cationization and the chain-end functionalized polymer. In addition, these molecular mass moments were consistent with moments determined by traditional methods.
