AbstractThe multimethod procedure for characterization of branched polydisperse polymers, including gel permeation chromatography, solution viscometry, melt viscometry, and differential scanning calorimetry, is described. An equation relating the average branching degreeg¯xand the average number of branch points n̄bxhas been derived and compared with the theoretical Zimm–Stockmayer equation. It has been found that both equations can be consistent for theta solvent and for the branching degree exponentb=1.5. Experimental data are given for trifunctionally branched bisphenol A polycarbon
