The product obtained is in liquid phase. For most cases water is taken as solvent.
Advantages Disadvantages Heat transfer easy due to presence of High mol. In this type apart from dispersed particles and dispersion media several other components are added. Usually the dispersion media is water. These droplets have the natural tendency to coalesce and gradually become larger and forms immiscible layer.
In order to discourage this tendency emulsifying agents such as soap like materials are added. Apart from that surface tension regulators, buffers, protective colloids are added to prevent pre-mature coalescence and precipitation of droplets of monomer as well as those of partially polymerized polymer by preventing adhesion of sticky drops. The emulsifying agents are substances with very low solubility in medium and therefore as its concentration is increased, the molecularly dispersed substances begins to form molecular aggregates known as micelles which exists either in spherical form or thin layer.
In micelles because of their hydrophilic and hydrophobic characteristics, the molecules orient themselves so as to have the tails towards centre and head towards water phase.
The concentration of emulsifying agent at which ion like molecules begin to form micelle is called critical micelle concentration CMC which changes the rate of change of physical properties When monomer is added which is organic in nature prefers the interior of the micelle because of organic environment. Micelle has the tendency to contract because of surface tension.
Hence the migration of monomer from monomer droplets to the interiors of micelle continues till equilibrium is reached between swelling and contracting tendencies.
When initiators are decomposed in water phase it bounces around the solution to create radicals. At this point the surface area presented by monomer-swollen micelle is much greater than monomer droplets so the probability for radicals to enter the monomer-swollen micelle is very high.
When the radicals enter the micelle it initiates the reaction. When polymerization takes place within micelle it lowers the concentration of monomer so that a gradient is established between monomer which in uninitiated and initiated one. Both diffuse.
Thus the uninitiated monomer swollen micelles gradually disappear losing their monomer content. View online Borrow download Freely available Show 0 more links Set up My libraries How do I set up "My libraries"?

Polymer characterization is concerned with the analysis of chemical structure, morphology, and the determination of physical properties in relation to compositional and structural parameters.
What is most unfortunate is that it appears to exist, not because of a lack of awareness but, rather, a lack of interest.
