An emulsion is a mixture of two or more liquids that are normally immiscible ... IUPAC. A fluid system in which liquid droplets are dispersed in a liquid.
Micro-emulsion polymerization: Emulsion polymerization in which the starting system is a micro-emulsion and the final latex comprises colloidal particles of polymer dispersed in an aqueous medium. Note : Diameters of polymer particles formed in the micro-emulsion polymerization usually are between 10 and 50 nm.
For example, a mixture that is 60% Water and 40% Oil can form an emulsion where the water is the dispersed phase and the oil is the continuous phase if the emulsifier is more soluble in the oil. This is because the continuous phase is the phase that can coalesce the fastest upon mixing, which means it is the phase that can diffuse the ...
The name "emulsion polymerization" is a misnomer that arises from a historical misconception. Rather than occurring in emulsion droplets, polymerization takes place in the latex/colloid particles that form spontaneously in the first few minutes of the process. These latex particles are typically 100 nm in size, and are made of many individual ...
A miniemulsion (also known as nanoemulsion) is a particular type of emulsion.A miniemulsion is obtained by ultrasonicating a mixture comprising two immiscible liquid phases (for example, oil and water), one or more surfactants and, possibly, one or more co-surfactants (typical examples are hexadecane or cetyl alcohol).
unstable emulsion of a soap bubble (at ambient temperature, with iridescent effect on light caused by evaporation of water; the suspension of liquids is still maintained by surfacic tension with the gas inside and outside the bubble and surfactants effects decreasing with evaporation; finally the bubble will pop when there's no more emulsion ...
As a dispersion in water (usually an emulsion), PVAc preparations are used as adhesives for porous materials, particularly for wood, paper, and cloth, and as a consolidant for porous building stone, in particular sandstone. [5] PVAc is considered a food-safe material, [6] and is thus used often in such applications (e.g., in food packaging ...
the reaction conditions can vary from bulk over solution, emulsion, miniemulsion to suspension; it is relatively inexpensive compared with competitive techniques; The steady-state concentration of the growing polymer chains is 10 −7 M by order of magnitude, and the average life time of an individual polymer radical before termination is about ...
