Flory distribution

http://www.polymerdatabase.com/polymer%20chemistry/Molecular%20Weight%20Distribution%20Stepgrowth.html The Flory–Schulz distribution is a discrete probability distribution named after Paul Flory and Günter Victor Schulz that describes the relative ratios of polymers of different length that occur in an ideal step-growth polymerization process. The probability mass function (pmf) for the mass fraction of chains of length is:
