The present invention relates to novel condensation polymers where N,N*-disubstituted disulfonamides are copolymerized with an organic acid dihalide such as dicarboxylic acid dichlorides, disulfonic acid dichlorides, bis chloroformates, diphosphoryl acid dichlorides, diphosphonyl acid dichlorides, or phosgene or with diisocyanates. The polymers obtained are thermoplastic and useful in molding and extrusion application.
