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
