摘要：
The initiation step of the light-induced polymerization kinetics of vinyl monomers using dye-sensitized photoinitiators to generate active radicals is discussed. The photoredox processes of basic dyes with amines and sulfinates are described as photochemical systems capable of starting free-radical polymerization of vinyl monomers in homogeneous and microheterogeneous media. Photophysical techniques like laser flash photolysis and time-correlated single photon counting are used to investigate the excited-state kinetics of the dyes.
