Poly‐ p ‐vinylbenzoic acid was polymerized from p ‐vinylbenzoic acid, and some of its physicochemical properties were studied (infrared and ultraviolet spectrum, solubility, density and refractive index increment in solutions, molecular weight). The polymer was readily transformed to poly‐ p ‐aminostyrene in a one step reaction by Schmidt transposition, in pure sulphuric acid. Polyampholytes were isolated and characterized at different stages of the reaction.
