A simple graphic method is described for obtaining average molecular weights of a continuously distributed polymer from its GPC chromatogram. The method is based on the assumption that the weight distribution of the polymer may be approximated by a Schulz distribution. As an example, a polystyrene sample is analyzed graphically, and the results are compared with the traditional method of calculation.
