Flory-schulz distribution
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

However, considering MWDs of real polymers, its importance is partly lost. Consequently, several problems arise.
