Differbetween
The two differences between emulsion and suspension polymerization are: 1) that a suspension polymerization is a mechanical process, and must have a stabilizing agent until the droplets are far apart, and 2) the emulsion polymerization is a chemical process which requires a surfactant to make the monomer "emulsify."

What is the difference between emulsion and suspension?
A few factors that can help differentiate between suspension and emulsion are: Phases: In a suspension, you can find two substances of any phase of matter like solid, liquid, and gas. At the same time, an emulsion consists of only two immiscible liquids. ... On the other hand, emulsions have two liquid phase particles.
What is the difference between solution polymerization and emulsion polymerization?
At the end, the emulsion latex particle is in fact an oil in water emulsion when aqueous. In solution polymerization, a processor dissolves a monomer in a suitable solvent, along with chain transfer agents and a free radical initiator.
What is meant by emulsion polymerization?
Emulsion polymerization is a polymerization process with different applications on the industrial and academic scale. It involves application of emulsifier to emulsify hydrophobic polymers through aqueous phase by amphipathic emulsifier, then generation of free radicals with either a water or oil soluble initiators.
What are types of polymerization?
There are two basic types of polymerization, chain-reaction (or addition) and step-reaction (or condensation) polymerization. One of the most common types of polymer reactions is chain-reaction (addition) polymerization. This type of polymerization is a three step process involving two chemical entities.
Does emulsion separate on standing?
"Emulsion" commonly refers to a mixture of two immiscible liquids, such as oil and water (or for example, olive oil and vinegar in salad dressing). It is common for regular suspensions and emulsions to phase separate on standing, so, given time, muddy water separates into a layer of mud with water on top.
What are two types of emulsions?
There are two basic types of emulsions: oil-in-water (O/W) and water-in-oil (W/O). These emulsions are exactly what they sound like, as pictured below. In every emulsion there is a continuous phase that suspends the droplets of the other element which is called the dispersed phase.
What are the advantages of emulsion?
The advantages of emulsion polymerization are that its use permits a rapid polymerization to a high molecular weight with narrow molecule weight distribution, the viscosity is typically lower than other methods, heat is relatively easy to remove from the reactor with water as the continuous phase and suitable for the ...
What emulsion means?
An emulsion is mixture of two liquids that would not normally mix. That is to say, a mixture of two immiscible liquids. By definition, an emulsion contains tiny particles of one liquid suspended in another. Chemically, they are colloids where both phases are liquids.
What is polymerization technique?
Introducing Polymerization. Several monomers combine chemically to form three dimensional networks or a chain of elements, and this process is known as Polymerization. These monomers can be the same or different compounds combining to form a polymer.
What is emulsion and its types?
Emulsions are the mixtures of two or more type of liquids where, one is such as droplets, of tiny or even ultramicroscopic size, which are distributed throughout each other. ... The unstable form of emulsions eventually separates into two forms of liquid layers.
What are two types of polymerization?
There are two general types of polymerization reactions: addition polymerization and condensation polymerization. In addition polymerization, the monomers add to one another in such a way that the polymer contains all the atoms of the starting monomers. Ethylene molecules are joined together in long chains.
How emulsion is formed?
An emulsion is formed when two nonsoluble liquids (e.g., an oil and water) are agitated together to disperse one liquid into the other, in the form of drops. ... It may occur in the oil reservoir itself or while flowing through pipelines, mechanical devices, such as pumps, and gas separators.
