| Abstract: | The theoretical basis for the determination of molecular weight distributions of polymers by gel-permeation chromatography has been investigated, using the previously developed theory of partition chromatography. Expressions determining the position and broadening of the concentration distribution in the elution curve have been deduced and the molecular weight dependence of the parameters characterizing the process has been considered. A method is proposed for determining the molecular weight distribution by a convolution procedure. |
