Abstract

AbstractMeasurement of molecular weight is an integral part of macromolecular and polymer characterization which usually has limitations. Herein, this article presents the use of a bench‐top 80 MHz Nuclear Magnetic Resonance (NMR) spectrometer for diffusion‐ordered spectroscopy as a practical and rapid approach for the determination of molecular weight/size using a novel solvent and polymer‐independent universal calibration.
