A series of polysulfonates containing aromatic imides was synthesized by the reaction of N,N''-bis(hydroxyalkyl) pyromellitic diimides or N,N''-bis(hydroxyalkyl)-3,3'',4,4''-benzophenonetetracarboxylic diimides with disulfonyl chlorides in pyridine. The structures of these poly(imide-sulfonate)s were identified by comparison of IR spectra with those of model compounds. Characteristic absorption bands of imide were observed at 1780-1770cm^-l, and 1730-1700cm-^-l and that of sulfonate at 1220-1190cm^-l. The inherent viscosities were in the range of 0.31-0.38 dl/g. These polymers were fairly insoluble in common organic solvents. Thermal stability of the polymers was also investigated.

N,N''-Bis(hydroxyalkyl)pyromellitic diimides 및 N,N''-bis(hydroxyalkyl)-3,3'',-4,4''-benzophenonetetracarboxylic diimides를 disulfonyl chlorides와 pyridine에서 반응하여 aromatic imide 구조를 갖는 polysulfonates를 합성하였다. 이들 po1y(imide-sulfonate)s의 구조는 model Compounds와 IR스펙트럼을 비교하여 확인하였으며 1780-1770cm^-1 및 1730-1700cm^-1에서 이미드의 특성밴드와 1220-1180cm^-1에서 술포네이트의 특성밴드가 나타났다. 얻어진 폴리머는 inherent viscosity가 0.31-0.38 d1/g의 값을 가졌으며 대부분의 유기용매애 잘 녹지 않았다. 또한 이들 폴리머의 열안정성에 대해서도 조사하였다.
