Webthe “most-probable” or Flory-Schulz distribution in which the weight fraction of Z-mers is given by w(Z) = ZpZ−1(1 − p)2, where p is related to the extent of reaction.[2,3] One of the drawbacks of such single-parameter distributions is that ﬁxing the mean of the distri-bution simultaneously ﬁxes its breadth.
