The dispersion phase diagrams (DPDs) are constructed In the form of contour plots.
(2) studying the ability of LD, in unchanged external impacts, to maintain for definite time the homogeneous distribution of the dispersion phase in the dispersion medium, that is, studying the sedimentation stability as discussed by Hodakov and Udkin [3].
In this paper, we introduce a model of close packing of the particles from the dispersion phase of the LD.
The empirical formula of Stokes for finding the radius of the equivalent spherical particles from the dispersion phase is well known as discussed by Hodakov and Udkin [3].
Dispersion phase diagrams of HASE-thickened Ti[O.sub.2] systems
Dispersion phase diagrams are useful for understanding the complex interactions of pigments with dispersants, associative thickeners, and surfactants.

One unique way to visualize the regions of pigment dispersion and flocculation in thickener-dispersant space is to use dispersion phase diagrams.
In this article, the effects of Ti[O.sub.2], dispersant, and associative thickener type on contrast ratio and gloss will be explored for model latex paints, but first the adsorption characteristics of the dispersants and thickeners and the dispersion phase diagrams need to be discussed.
It was also found that in a nylon 6/ABS system, a suitable amount of compatibilizer helps disperse the ABS in the nylon 6 phase, as well as reducing the particle size of the ABS in the dispersion phase (4).
With the addition of POE-g-MA, the ABS copolymer dispersed uniformly in the nylon 6 phase, and the size of ABS particles in the dispersion phase was apparently reduced.
Surface etching of specimens for SEM analysis is usually carried out with a selective solvent for the dispersion phase. We tried to etch the starch phase using water, which is capable of swelling the starch domain.
