Abstract Pyrazine mono‐ and di‐ N ‐oxide chromophores included in a polymeric chain induce its photoreticulation. Photosensitivity is higher for dioxidized samples than for monoxidized ones. The mechanism of photocrosslinking is different from the one which proceeds photoreticulation of polymeric chains containing pyridine N ‐oxide groups.
