To achieve any high molecular weight polymer, the fractional conversion must exceed 0.99, and the dispersity of this reaction mechanism in a batch or PFR is 2.0.
22.
The latter usually have a range of molar masses ( unit g mol " 1 ), the distributions of which are indicated by dispersity ( " " ).
23.
For FRPs that have a constant monomer and initiator concentration, such that the DP n is constant, the dispersity of the resulting monomer is between 1.5 and 2.0.
24.
Dispersity is represented by the symbol , and is a measure of the heterogeneity of sizes of molecules or particles in a mixture, referring to either molecular mass or degree of polymerization.
25.
Since the anionic polymerization dispersity for a batch reactor or PFR is basically monodisperse, the molecular weight distribution takes on the distribution of the CSTR residence times, resulting in a dispersity of 2.

Erlewine mentioned Nelson's dispersity through the tracks, stating that he " has no innate editor . . . but when he does connect, it's a wonder to behold ".
28.
The dispersity ( also known as the " polydispersity index " ) of a sample is defined as M w divided by M n and gives an indication just how narrow a distribution is.
29.
The density at which systems jam is determined by many factors, including the shape of their components, the deformability of the particles, frictional interparticle forces, and the degree of dispersity of the system.

In rheology, the "'Farris Effect "'describes the decrease of the viscosity of a suspension upon increasing the dispersity of the solid additive, at constant volume fraction of the solid additive.
