Keratin vinyl

In this last study it was shown that the luminescence emission from wool keratin is very similar to that from tryptophan in a solid poly(vinyl alcohol) film, which thus provides a useful model system. In both cases the triplet state could be readily studied both at 77 and ambient temperatures by emission and absorption spectroscopy. 

Mercaptan groups in keratin fibers also undergo nucleophilic addition reactions with active olefins (olefins containing a strong electron-withdrawing group attached to the double bond). Schoberl [91] has shown that reduced wool fiber reacts with vinyl sulfones. 

Difunctional reagents containing two active vinyl groups are capable of reacting with reduced keratin hbers and forming cross-links. Divinyl sulfone has been used for this purpose [91],...
