Electrospray ionization mass spectrometry has been demonstrated to be a useful technique for the molecular weight determination of a Starburst polymer. Mass spectra of multiply charged ions are deconvoluted to provide molecular weight information of many components in a non‐separated mixture. These data may also be used for determining a polydispersity value for this systhetic polymer system.
