WebAlkenes: Polymerization Polymerization is a process by which an organic compound reacts with itself to form a high‐molecular‐weight compound composed of repeating units of the … WebAddition polymers include polystyrene, polyethylene, polyacrylates, and methacrylates. Condensation polymers are formed by the reaction of bi- or polyfunctional molecules, with the elimination of some small molecule (such as water) as a by-product. Examples include polyester, polyamide, polyurethane, and polysiloxane.
