Aromatic polysulfonamides |
|
| Authors: | F E Arnold S Cantor C S Marvel |
| Abstract: | Aromatic polysulfonamides have been prepared by solution polycondensation of aromatic disulfonyl chlorides and aromatic diamines with a suitable acid acceptor in such solvents as N,N-dimethylacetamide and tetramethylenesulfone. The highest molecular weight polymers were obtained by using 2,6-dimethylpyridine as the acid acceptor in tetramethylenesulfone as the solvent. Clear, translucent, brittle films of the polysulfonamides may be formed from solution or from melt. |
