POLYDISPERSITY INDICES OF LINEAR POLYMERS MELTS FROM RHEOLOGICAL MEASUREMENTS

Abstract

We present here a method for determining the polydispersity indices Ip1=Mw/Mn and Ip2=Mz/Mw of the molecular weight distribution (MWD) for linear, entangled, polymers melts, in a direct manner, as a previous step for further characterization of polymeric
