摘要：

It has been shown that the parameters in the log‐normal (LN) and generalized exponential (Gex) distributions can be evaluated if molecular weight ratios H and Hz, or their equivalents, are known for a linear, unimodal homopolymer. It is suggested that better checks of observed and calculated values of Mz can be obtained for such polymers as are characterized by m ≤ 0.15, by treating them as Gex rather than LN distributions.
