Photodissociative and electron-transfer photoinitiators of radical polymerization

Polimery 1999, No 3, 161


DOI: dx.doi.org/10.14314/polimery.1999.161

Summary

Photoinitiation of polymerization is reviewed, including Author's own data, covering factors like absorption of radiation, bond energy, solvent effect, and photosensibilization. Photoinitiators are classified into two principal groups, a and b, which dissociate to yield compounds that split the bond in position a or b with respect, e.g., to the carbonyl group. A general kinetic description of photoinduced radical polymerization is given and the mechanisms and the kinetics of photoinduced intermolecular electron transfer in the process of photoinitiation of radical polymerization are discussed.


Keywords: photoinitiated radical polymerization, photodissociative photoinitiators, kinetics of photoinduced polymerization, photoinduced intermolecular electron transfer, mechanisms
