NOVEL POLYELECTROLYTE COMPLEXES BASED ON DIAZO-RESINS

Polyelectrolyte complexes containing diazonium groups (PEC-N-2) with a high ionic crosslinking rate were prepared as a precipitate by mixing the diazo-resin with polyanion solutions. The photochemical decomposi tion of the complexes from different polyanions was studied. It was sh own that PEC-N-2 exhibit high photosensitive properties. Under irradia tion of UV light, the complexes which can be dissolved in ternary mixt ures such as H2O-DMF-LiCl,H2O-DMF-NaSCN or H2O-DMF-ZnCl2 (DMF: N,N-dim ethylformamide) become indissoluble since the crosslinking structure o f the complexes changes from ionic to covalent.
