Study Notes
Initiators in Polymerization
- Initiators are substances that start the polymerization reaction by forming active sites on the polymer chain
Types of Polymerization
- Living polymerization: proceeds exclusively by reaction between the monomer and active side on the polymer chain
Kinetic Chain Reaction of Addition Polymerization
- Main steps:
- Initiation: formation of active sites on the polymer chain
- Propagation: continuous addition of monomers to the active site, leading to chain growth
- Termination: reaction that stops the chain growth, resulting in the formation of a polymer molecule
Types of Addition Polymerization
- Free radical polymerization: involves the use of free radicals as initiators
Function of Thermal Initiators
- Thermal initiators: decompose into free radicals when heated, which then initiate the polymerization reaction
