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 …

WebNov 1, 1996 · The polydispersity index as a measure of the width of molecular weight distributions (MWD) is theoretically very important. However, considering MWDs of real polymers, its importance is partly lost. Consequently, several problems arise. The most common one is the misinterpretation of polydispersity index as a single and unique … daddy longlegs crosswordWebDec 1, 2024 · In this work, we introduce a new cure rate model based on the Flory–Schulz (F-S) distribution. The motivations to introduce this model are: (1) The F-S has a PGF in a simple and closer form, very useful in this cure rate model context; (2) P(M=0)=?[sup.2] also has a simple form. This allows one to, among other things, reparametrize the model ... daddy long legs definitionWebThis particular distribution is known as the flat Dirichlet distribution.
