Polymer chain reaction
WebPolymers are large molecules constructed from many smaller structural units called monomers which are covalently bonded together. In chemistry repeating unit is the unit that periodically repeats itself along the polymer chain. Most of the time the repeating unit is nearly equivalent to the monomer. Basically, the properties of polymers depend ...

WebAn initiation reaction must occur to functionalize a monomer unit before the reaction can begin. Once a monomer has been functionalized, another monomer unit can bind to it, and the functionalized carbon center propagates to the new monomer unit. In this fashion, monomer units continue to attach to the polymer chain until termination occurs. WebChain transfer is a termination reaction by which the free-radical site of a growing polymer chain is transferred to another molecule: R r · + S → P r + S·. The newly formed solvent or monomer radicals may then reinitiate chain growth by resumption or propagation reactions: S· + M → R 1 ·. R 1 · + M → R 2 etc.
