| 摘要 |
This invention relates to an improved process for producing weakly acidic cation exchange resins, in particular the purification of weakly acidic cation exchange resins derived from crosslinked poly(acrylonitrile) and also the use of steam for reducing the leaching of weakly acidic cation exchangers and finally a process for increasing the performance of water treatment systems, preferably of tap water treatment systems, using the weakly acidic cation exchangers produced according to the invention.
