Abstract

Polystyrene polysulphon - (p - o - cyanacetylanilido)-polysulphonic acid is prepared by sulphonating polystyrene in ethylene dichloride with sulphuric acid, treating the polysulphonic acid thus obtained with chlorosulphonic acid, and reacting the chlorosulpho-groups thus introduced with p-o -cyanacetylaniline. Specifications 479,838, 593,088 and 747,589 also are referred to.
