The numerical evaluation of parameters in distribution functions of polymers from their molecular weight distributions

摘要

AbstractIt 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 Mzcan be obtained for such polymers as are characterized bym≤ 0.15, by treating them as Gex rather than LN distributi
