Process for the alkaline saponification of crosslinked acrylonitrile bead polymers |
| abstract |
The alkaline saponification of acrylonitrile bead polymers provides weakly acidic cation exchangers with little intrinsic color and with reduced residual nitrogen content if the saponification is begun at a temperature T1 of from 70 to 120° C. and, once a degree of saponification of at least 65% has been reached, is completed at a temperature T2 of from 120 to 180° C. |
