Abstract Direct measurement of intrinsic viscosity on gel permeation chromatography effluent was performed with use of an automatic viscometer in order to determine molecular characteristics of branched polymers. In analyzing the viscosity data, the instrumental spreading was considered. Results obtained from three low‐density and one high‐density polyethylene were compared with those obtained by such other methods as osmometer, light scattering, and column elution fractionation.
