emulsion polymerization

Emulsion polymerization is a process used to create plastics and synthetic rubber where tiny water droplets contain dissolved monomers (building blocks). These droplets act as tiny reactors, with special agents called surfactants stabilizing them. When a initiator (starter chemical) is added, it triggers the monomers to link together, forming polymer chains inside the droplets. As more monomers join, they create large, suspended polymer particles—think of small rubber or plastic beads—that remain dispersed in water. This method produces smooth, consistent materials used in products like paints, adhesives, and rubber goods, efficiently combining water, monomers, and stabilizers.
