A method for estimating the rejection coefficient-molecular weight relationship of ultrafiltration membrane for a chain polymer by using gel permeation chromatography.
An improved method is presented for estimating rejection coefficient-molecular weight relationship of an ultrafiltration membrane for a polydisperse chain polymer. It is based on the basic idea using gel permeation chromatography originally developed by Cooper and Van Derveer. The method, in which peak spreading of an elution curve of the polymer was taken into consideration, is available for evaluating the relationship over a wide range of the molecular weight through only one experiment in analyses of the retentate and filtrate.
