摘要
Polymers obtained from photosensitive copolymerizable systems show outstanding reactivity and durability. Excited state properties of photoinitiators containing unsaturated ethylenic groups have been studied by nanosecond time-resolved laser-spectroscopy, with respect to triplet state lifetimes, rate constants of interaction with the environment (oxygen, amines, monomers). Measurements of rates of polymerization (R(p)) in solution (at various monomer concentrations [M]) allowed comparison of the theoretical dependence of R(p) on [M] with the experimental results. Correlations are established and discussed.
