A~traet--Polyamideimides having sulphonamide linkages were prepared by low temperature polycondensation of 2-sulphoxy-l,3-dioxoisoindoline-5-carboxylic acid with various diamines in the presence of thionyl chloride. The polymers were soluble in highly polar solvents. The solubility parameters of the
