Flory schulz distribution

WebFeb 3, 2024 · Linear α-olefins or LAOs are produced by the catalytic oligomerisation of ethylene on a multimillion ton scale annually. A range of LAOs is typically obtained with varying chain lengths which follow a distribution. Depending on the catalyst, various types of distributions have been identified, such as Schulz–Flory, Poisson, alternating and … WebThe simplest and most widely used is the Anderson–Schulz–Flory (ASF) model, 1 where the FT reaction is modeled as an addition polymerization reaction with chain growth probability α. The resulting product distribution, depicted as a plot of the logarithmic molar fraction versus the carbon number (‘ASF-plot’), is a straight line.
