摘要：

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 synthetic polymer system.
