Desonide-loaded nanocapsule suspensions used in this study prepared with different polymers had mean diameter and polydispersity index values in accordance with that expected for these systems [16, 20].
Caption: FIGURE 4: (a) Effect on particle diameter, polydispersity index of varying of the content of PFOB, the concentration of LutrolF68, the concentration of LutrolF68, and the concentration of oleic acid; (b) effect on particle diameter and zeta potential of varying of the content of PFOB, the concentration of LutrolF68, the concentration of LutrolF68, and the concentration of oleic acid.
Table 1 summarized the results of polydispersity index obtained from GPC analysis.
The mean droplet size and polydispersity index of the reconstituted microemulsions are presented in Table III.
Both types of particles are nearly monodisperse: polydispersity index (PI) = 0.
The polymers made with these techniques are not only defined by their composition, molecular weight, and polydispersity index, but also by their synthesis method--demonstrated with two AB block copolymer dispersants prepared by GTP and ATRP.
Yoo explained that the company has been working on the development of more sophisticated rheological analysis using frequency sweeps, which allows better determination of the polydispersity index (PI) of a resin, an excellent measure of the molecular weight distribution of a polymer and its viscosity.
The diene elastomer exhibits a monomodal distribution of molecular weights before functionalization and a polydispersity index before functionalization of less than or equal to 1.
In this study, our aims are to compare THPS and MAPS methods between themselves, and investigate the effect of temperature in MAPS method at different parameters such as reaction times, weight average molecular weight (M w ), polydispersity index (PDI), hydrodynamic radius (Rh), intrinsic viscosity ([e]) and Mark Houwink equation constant (a) of copolymers.
