WebThe Flory–Schulz distribution is a discrete probability distribution named after Paul Flory and 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: .

WebThis particular distribution is known as the flat Dirichlet distribution. Values of the concentration parameter above 1 prefer variates that are dense, evenly distributed distributions, i.e. all the values within a single sample are similar to each other. Values of the concentration parameter below 1 prefer sparse distributions, i.e. most of ... WebThe Schulz–Flory distribution is a mathematical function that describes the relative ratios of polymers of different length after a polymerization process, based on their relative probabilities of occurrence. Carbon nanotubes (CNTs) are big carbon molecules which have a very high length-to-diameter ratio, somewhat similar to polymer molecules WebMay 1, 2024 · The typical FT product distribution follows that of Anderson-Schulz-Flory. Consequently, the mathematical model was developed to follow the ASF distribution, which is expressed by the Eq. (2), where M i is the molar fraction of compounds having the number of carbon atoms of i [29]. (2) M i = α i-1 1-α how to roll a neckerchief
