Addition Polymerization Process
Addition polymerization is a process where monomers with carbon-carbon double bonds combine rapidly to form long-chain polymers. During this process, the polymer chain grows as each monomer adds onto the active site, extending the chain step by step. You can think of this as a chain reaction, where the growth continues until no more monomers are available. Catalysts play an essential role here—they help initiate the reaction and speed up the polymerization process without being consumed. They guarantee that the polymer chain grows efficiently and uniformly. This method produces polymers with consistent structures, like polyethylene and polystyrene. Understanding the polymer chain growth and catalyst roles helps you grasp how addition polymers are formed quickly and with control over their properties.
Condensation Polymerization Method
Condensation polymerization occurs when monomers with two or more reactive groups combine, releasing small molecules such as water or methanol as byproducts. This process often leads to complex structures, including polymer chain branching and cross-linking effects, which influence material properties. To understand it better:
- You’ll see how polymer chains grow through stepwise reactions, creating networks that can be highly branched or cross-linked.
