Webdistribution of a polymer, and is defined by: Polydispersity index = Mw Mn The larger the polydispersity index, the broader the molecular weight. A monodisperse polymer where all the chain lengths are equal (such as a protein) has an Mw/Mn = 1. The best controlled synthetic polymers (narrow polymers used for calibrations) have Mw/Mn of 1.02 to ... WebThere’s Osterman product in stock and waiting to ship from over 100 locations.
