Main Difference – Suspension vs Emulsion Polymerization
Suspension polymerization is a type of radical polymerization in which mechanical agitation is used. Here, the monomers should be in the liquid phase. There can be either one monomer or several monomers present in the liquid mixture. When polymers are formed from this method, the polymer material exists as a sphere suspended in the liquid.
Four Polymerization Techniques (Bulk,Solution,Suspension and Emulsion)
At Mallard Creek Polymers, we have built a globally-respected business on delivering the finest emulsion polymer formulations for our clients in multiple industries for hundreds of applications. People often ask us, “What’s the difference between emulsion polymers and solution polymers?” This article will offer a little clarity on the differences between these two manufacturing mainstays.
What is the difference between suspension, emulsion and colloidal solution?
A suspension is a heterogeneous mixture of solid particle in carrier liquid. It is not dissolved it is suspended. The emulsion is the mixture of two or more immiscible liquids. E.g. Water and oil, soap and water. A colloidal solution is the mixture of sub micronic particles in carrier liquid.The particles are kept in suspension through brownian motion.
Although this method is very similar to suspension polymerization, the two schemes differ in two important aspects; the polymerization initiator is located in the aqueous phase and the particles of polymer produced are typically in the order of 0.1 micron in diameter, some ten times smaller than the smallest encountered in suspension polymerization.

Difference Between Suspension and Emulsion Polymerization
The key difference between suspension and emulsion polymerization is that mechanical agitation is used in suspension polymerization while emulsion polymerization usually occurs in an emulsion.
From suspension toward emulsion and mini-emulsion polymerisation to control particle size, particle size distribution, and sphereness of printing toner
Assessment of particle size, particle size distribution and reaction conversion visualised the potential of suspension, emulsion and mini-emulsion polymerisation techniques to control microstructure, and colour characteristics of synthesized toners as well.
