✦ Synopsis

Polyelectrolyte complexes containing diazonium groups (PEC-N2) with a high ionic crosslinking rate were prepared as a precipitate by mixing the diazo-resin with polyanion solutions. The photochemical decomposition of the complexes from different polyanions was studied. It was shown that PEC-N2 exhibit high photosensitive properties. Under irradiation of UV light, the complexes which can be dissolved in ternary mixtures such as H,O-DMF-LiCl,H,O-DMF-NaSCN or H20-DMF-ZnCl2 (DMF N,N-dimethylformamide) become indissoluble since the crosslinking structure of the complexes changes from ionic to covalent.
