Weakly acid cation exchange resin |
摘要 |
Preparation of a weak acid cation exchanger from polymethacrylic acid comprises: hardening a monomer mixture from methacrylic acid alkylester, methacrylic acid, crosslinker, radical initiator and optionally porogen through suspension polymerization in aqueous phase to form a pearl polymer; and alkaline saponifying the pearl polymer at 100-160[deg]C. An independent claim is included for a weakly acidic cationic exchanger from polymethacrylic acid, which is obtained by the above method. |
