Functional group conversions obtained in the process of photo-formation of various types of IPN networks, using photoinitiating systems based on bis-(4-t-butylphenyl)iodonium hexafluorophosphate (1 wt%) and 2-(diethylamino)-4-(1-ethylpropyl)-6-phenyl-benzene-1,3-dicarbonitrile derivatives (0.1 wt%), determined by real-time FT-IR.
