The preparation and properties of a group of light‐sensitive polymers formed from poly(vinyl sulfonates) quaternized with 4‐picoline and allowed to react with various aldehydes, especially anisaldehyde and 2‐furaldehyde, are discussed. The polymers are alternatively prepared by quaternization of styrylpyridines (stilbazole) with poly(vinyl arylsulfonate) esters.
