index (PDI) was acquired with a PL-GPC50 gel permeation chromatograph.
(a) DLS of colloidal silver dissolved in water showed an average size of 100 nm with a polydispersity
index of 0.2.
Subsequently, a polycondensation reaction at an elevated temperature is carried out (usually at about 250[degree]C), with the use of an appropriate catalyst, resulting in a polycondensate mixture with a relatively high polydispersity
. This method is not directly applicable to carbohydrates such as sucrose and inulin because these carbohydrates decompose at such high temperatures, and are not easily miscible with fatty acid methyl esters or oils.
Long-Oil Alkyd Resin Composition, Molecular Weight, and Polydispersity
The rigorous expressions for spinodal and critical points, considering the polydispersity
of polymers, were derived by Koningsveld and Staverman :
Nanoparticle characteristics such as particle size, polydispersity
index and zeta potential were evaluated.
Measurements of Photochromic Nanocapsules Size and Polydispersity
The number average molecular weights (Mn) and polydispersity
index (P.I) of the polymer samples are given in the last two columns of Table 1.
The low-density metallocene polyethylene has 50,000 to 200,000 number average molecular weight and low polydispersity
. The amount of low-density metallocene resin added to the regrind layer is 3 to 20 wt%.
The average molecular weights were [M.sub.n] = 3350 and [M.sub.w] = 8380, and polydispersity
For samples with polydispersity
(PD) greater than about 1.5, these differences can significantly impact the analysis.
Researchers also want to determine polysaccharide molecular weight and polydispersity
using a combination of total intensity light scattering and quasielastic light scattering techniques.
