The particle surface of fluorosilica is rough, which can be explained by Smoluchowski coagulation relationship (31), in which to the aggregation into larger coacervate occurs during the growth of primary particles results in larger particles.
In order to overcome this problem, we can make use of momentary and partial high temperature and high pressure produced by supersonic cavatition, KH-570 added as dispersing agent, to disperse SiO2 coacervate.
Low polymer concentration resulted in decreased inner phase viscosity, which might efficiently promote the break-up of coacervate droplets and prevent coalescence.
The coacervate so formed was hardened with 25% glutaraldehyde (1.
Diffusion characteristics and properties of chitosan coacervate capsules.
Furthermore, there are indications of critical concentrations for each of these components and that in the entangled region, the modulus of the coacervate is that of a crosslinked gel, whereas in the dilute region, the coacervate is a viscous liquid.

As the pH was altered and crosslinking occurred a dense coacervate shell encapsulated the core material.
Hydrophobically modified cationic polymers were also studied with respect to the structure of the lyotropic association colloid within the complex coacervate.
It is comprised of a cationic polymer comprising cationic protonated amine or quaternary' ammonium functionalities comprising dialkylaminoalkyl acrylates, dialkylaminoalkyl methacrylates, monoalkylaminoalkyl acrylates, monoalkylamino alkyl methacrylates, trialkyl methacryloxyalkyl ammonium sails, trialkyl acryloxyalkyl ammonium salts, diallyl quaternary ammonium salts, pyridinium moeities, imidazolium moeities, quaternized pyrrolidone moeities, and mixture thereof; an encapsulated anionic colorant selected from the group consisting of FD&C Yellow 5, D&CYellow 10, D&C Red 33, D&C Green 5, D&CYellow 8, D&C Red 28, and mixtures thereof; and an aqueous carrier; wherein the cationic polymer forms a coacervate with the encapsulated anionic colorant.
