Macromolecular Materials and Engineering, Volume 310, Issue 12, December 2025.This exploratory study investigates the reversible cross‐linking of polyamide 6 by the photolabile cross‐linker 1‐(5‐(Aminoethyl)‐2‐nitrophenyl)ethanol (PXL). The storage modulus of the material increases with increasing PXL content and decreases when the exposure time of the samples is increased.
