Abstract
A rapid analysis method for the determination of polymer average molecular weight separates the polymer's high molecular weight fraction and determines its average molecular weight using a molar mass detector and a concentration detector. The method avoids time consuming sample preparation, allows for separation of interfering low molecular weight components, and is suitable for automation.
