GPC data for long‐chain branched polymers (low‐density polyethylene) are interpreted with the aid of a polynomial expression for intrinsic viscosity in terms of the molecular weight. The resulting molecular weight distribution curves agree well with those derived in an earlier work based on certain assumptions regarding the degree of long‐chain branching.
