Controlled Polymerization Reagents (Other) (186)

Controlled polymerization reagents are substances employed to manage the growth of polymer chains during polymerization. They play a critical role in determining the molecular weight and polydispersity index of polymers. These reagents function by regulating the rate of monomer addition or halting chain growth at a desired stage. They are extensively utilized in the production of advanced materials like block copolymers and hydrogels. Common examples include activated catalysts, chain transfer agents, and free radical scavengers.
