Emulsion Polymerization: In this process, monomers are suspended in water, and a surfactant is used to stabilize the emulsion. Initiators then trigger polymerization, resulting in the formation of latex particles. This method is commonly employed for producing synthetic rubbers like styrene-butadiene rubber (SBR) and nitrile rubber (NBR).

Solution Polymerization: Monomers are dissolved in a solvent in this method, and polymerization occurs in the solution. The resulting polymer is then precipitated, washed, and dried.
